APPLICATIONS OF MICRO ACTUATOR || EC 465 MEMS || S7 ECE KTU || LECT 6

Hi students today, we are discussing about the applications of micro AGTs So first one micro grippies micro gripper and the animal come There a micro robotics level a essential component on a micro gripper I'm sorry, so there are no micro assembly level of a surgery. I'm a lot more you see in a micro grippies I'm the rain man, I don't render a gripping methods on the first one on the right another Electrodes in normal plate I'd allow electrodes you see the tola gripper on The first a figure a country in Iran can the render electrodes and electrodes Connected even though, you know parallel I'd honor connected even natural a normal plate electrodes to see the tola micro gripping You know the other Sardana you see our la carnava The other my type micro gripper in a cooter than space avisham. I don't know the most other net other you see our la random method and the Sliding plate electrode you see the tola and sliding below it electrode. You see the tola the Sardana at common I'd You see in the one micro gripper and sliding plate you see the tola micro gripper We can do electrodes in the rain with the slide. You know, you did a random Cherry, I'm going to know to marry it again. They are Other than a popular method and the other is sliding plate. You see the tola micro gripper The is sliding and gripper on a southern at a combo drive actuator element to Mellon you see in the sliding a plate electrodes you see the tola micro grippers Apple figure a conundrum to a typical micro gripper on a combo drive actuators You see the tola micro gripping on a figure a conundrum You know the no conundrum to another arrangements Arrangement of fingers are like comb another fingers finger electrodes alum connected The two sets of comb architectures are arranged in such a way that the fingers are inter digital fashion fingers alum and inter digital Fashion and I'm arranging the kingdom Well, we apply some external force the combs come closer and thereby the arms connected to combs are Closer and work like a gripper But I didn't a thought to the malaria external for supply chain betta come me combs and a low Machi pola regina, that's close. Oh, you know, it's a audit thought. Oh, but I didn't moment assembly You know, I drive a man to array in the other end of drive a man to array in the Moment assembly moment assembly in betta. Got it. Move below to me. You know, I'm gonna suppose a move below to me in betta And I know so we item a gripper and a 10 micrometer in the burn a connection in a gripper I'm gripper moon or to me in an answer to our gripper and the Agripper and a combs and are in a close on betta come other and I'd work in a gripper Working. Okay, then I'm very thrilled. Oh, well, we apply the external force the combs comes closer and thereby the arms connected to combs comes Closer and work like a gripper. I'm gonna even die to work a very gripper. Well, I'm working upon It on Again, I know a comb drive. I use a micro gripper with comb drive actuators working Oh, you know, but I'm gonna drastic reduction in actuation voltage with the ink increase of number of pairs of electrodes The other user the original Electrodes in the end, I'm gonna cook it. I know I'm gonna apply chain of voice I'm gonna apply chain of old age in the am but I'm ready you see It's a matter of cooking the electrodes and I'm cooking in a message I'm a cook a little cook and I didn't actually I'm ready to do my cook in the old age. I'm a cook Reduce a amad. I didn't a graph on a reduction in voltage With respect to number of electrode pairs. I'm not a lot more than in the search Voltage I think would have been the old age in the rain I know I wish I know drive a PM and in the world age in the rain the am but Reduce Transverse comb drive Transverse comb drive in the diagram on It in the case a little more Figurine, you know, can I know a flexible beam got another flexible beam in the area of the flexible beam about if flexible beam in a moment is Another mechanism in this given figure a comb architecture with a flexible beam is placed with another fixed comb mechanism But I'm gonna be the electric voice up like a in the summit of flexible comb in a moment It's a movie game. I'm gonna I let roads in the gap reduce ENG our radio LAN Transverse comb drive working We would a moment is a big enough flexible beam in a region. I'm going to raise channel force a flame of data flexible comb comb mechanism moves in horizontal direction a flexible comb mechanism horizontal direction emoji and thereby reducing the gap between inter-electrodes interdigital electrodes and inter-electrode interdigital electrodes in today's gap cork ENG You are a stretcher in a on a number of them. No, it's in the transverse comb drive architecture in the weekend in a to the micro motors of a micro mortise Come a micro motor angle. I am working in that. I'm gonna work in the in the way to enjoy But a core electrodes on the electrode I plates Electrically charged the plates. I'll include electrodes missile a night again Our missile a night again electric Electrodes alien J and ceramic in the end of our commodity on a micro motor working So unlike traditional mortise the driving forces for micro mortise is primary primarily the parallel electrostatic voices between pairs of Miss Alain the electrically charged the plates or electrodes as will be Demonstrated in the following two cases mean item Tented that a little a micro mortise on all of the one linear stepping mortise Um, and I'm at the rotatory mortise So in the case of linear stepping motor here We are using two sets of electrodes in the form of plates separated by a die lettering material and The Set of electrodes on all of the one I'm gonna the moving set electrode and the fixed set electrode here and set electrode on all of the Ave separate either to a die lettering material on the die lettering material at quads when on UCM Pum either not over a set in the rain and on a fixed and on a matter than the rain with a mobile on a Asset a mobile setting in a moment assembly again a Continuous motion it another possible I play with a step size of the motion on the brain with a W by three on a step size I'm not a general the size of preset mismatch of pitch between two Electrodes it and electrode settler the middle of each and on down our slide Variation in the rain and on a W by three in the variation But I don't even know working a on the name One of the fixed electrode I reek in matter the mobile electrode I reek in the area and the gun on die lettering material I got on quads again. You can die lettering material I to you see in the number Energy is a genius. I'm a little and I'm a made a shroom They will be made a show a lot number land on the pitch difference on the W plus three W by three in the brain or a pitch difference Lana Melilla la moving set electrodes a land shade the Ricci No, I'm gonna very much a come and the end the energy is a chain of Samantha It's a land chain srama not a team. I didn't a fog of my it. I would a continuous movement Energy, you really and the I Linear stepping mortise working near the rotatory stepping water and rotatory stepping water and more a Other a rotation a Ricci order moment, and I can other metal in your iPad and welcome to an animal moment. I don't know Madam, you would add a random set on the earth I'm gonna near the Avada linear and I guess it'll run a fix it'll run a mobile Oh, yeah, you would add a ball on the end of the city electrodes on the What is it in a parade in the parade a rotor on the matters that in a parade a State it on the water Rotor in the rain in the samba and the other kind of a good rotation that I can Tell you in the other semester terror on the rain in the area can fix it I need a rotary name stator in a separate either the matter that the Fix it in a mobile in a separate either to turn the iron or die electric If it ever they will a an Rotary name stator a name separate either to a dielectric material on the other Southern a to die electric in the rain in the air on even a in the case in a dielectric material But even a new model figure not to look again. You know, Mr. I mean you would have channeled a land on a kind of a the Ninger strategy to look again. You know, I'm gonna get it another gonna Channel the other end on a rotor and stator mark either can I know rotor stator? Very figure not Rotor and stator or a alien item to another window near a top near a south Anna Adityanath Adityanath another and the la la la la Pinna veranda another alien down pinna random at the nother alien de la pinna veranda De alien de la pinna a random at the alien de la a ready la irium it enough Same thing. Yeah, you've got a I'm from stator. I'm a Difference matrimony the nother paranoid. If you carry Canada or a germany-led nuclear center research central develop either a micro motor in the figure on a So the electrostatic micro motor and a working on a concierge in the other electrostatic One of the first electrostatic Micro motor principal operation Central a Rotor on the pinnary stator among the number Adam the nother central rotor in a recharging a they will a radial stator in a radial stator in a opposite polarity charge Adam the nother six stator phases on a Rotating another another one two, three, four five six the name one two, three, four five six and I shall Six stator phase I turn a little bit of it again That's an R pair poles on the another either on a VM of a VM He pulls on a VM of a VM gene database is a lie again with a rotate Rotation possible One No, no, no, no, no, no, no, no Adela and Anna They're over in the other Kayla movement in the middle In a two and the rain with a one I got a two and the rain there and run on I got a number blue blue I can see you know there are two aligned on Allelu to a land a land a two and then a sramikam Alien J and sramikam to a land J and sramikam betta gum and the sambar gum I'm not a clockwise lot or a moment of it. I'm not a Adam other two and the other and the other figure in Canada among other figure a condor to and the rain that and I aligned I to a land I betta go one No, I didn't stretch and the other but to move either with one in the alignment way of the nokanda to aligned I Any other face in the rain and they're even three aligned I know a three key and then a three win and then a sramikam a land J and sramikam I'm gonna bring betta gum out of the three I'm gonna I read it in a land I do it three a land I do it in the fog might end the Adam We're clockwise. I told a moment Adam. This is the working of electrostatic micro motor Adam Application Circular in geometry 2.5 millimeter diameter 10 micro meter thickness a Little bit actually to J and we need to know that the one window opening and closing you and I'm controlling Thermal force on a heating drinks and orange another Kano electrical resistance heating drinks in the country Then I would a generator Jina a very thermal force Um again, I'm either at the valve in the valve working on the flow control and carrying glamilla Heating ring aluminum films you see that I know that under five micrometer thickness or la Aluminum films you see that on a heat and ring They believe in the capacity and or a 300 cubic centimeter per minute and then the capacity in the rain other other than a particular fluid pressure relay 300 cubic centimeter fluid pressure of 100 Pound voice per square inch I read a pressure on the rain with a power consumption in the rain I don't know 1.5 watt I read Power consumption near to them in the micro pumps Micro pump may not enter either micro pumps are available at one of the rain that electrostatically Agitated micro pump and other piece of electrically agitated micro pump. I get the electrostatically agitated micro pump The Square geometry on a pump in electrostatically agitated micro pump another four millimeter into four millimeter into 25 micrometer thickness or another either on a micro pump designed it or not been a Diaphragm other well a lot roads in the middle of the form micrometer in the gap on the When a pumping rate on the rain that the 70 micro liter per minute at 25 Hertz I recommend against a lot of pumping rate in a type of pump a on a micro pump on a piece of electrically agitated pump Then at the end I read him piece of electric material I read him number you see in the An effective way to pump fluid through capillary tubes. I know many to use a another number piece of electrically agitated pump on a Then I guess it to boil in the rain with a flexible I read you know Flexible I told her to boil on the tube oil in the outside item on the coating a piece electric crystal Crystal film image and a tube oil in the outside item on the coating number radio frequency voltage is another dark voltage apply a medium I enter digital transducers or a mechanical squeezing possible I'm gonna let to paste another A Nakuna very same on a squeezing of toothpaste at a boiler that I did another ideal pump be piece of electric coating our transducer another ideal and on a mechanical squeezing a variety in this fog a mite Avery pumping mechanism look on a piece of electric agitated pump in the working area a little the micro accelerometer Accelerometers are used to measure dynamic forces associated with moving objects The accelerometer and limited on a vegan moving objects in the forces measure a and when it on a number a Dynamic forces measure a and when it on a number accelerometer You see in the forces in the rightness of the night a relative of the velocity I'm able to acceleration a carry can be moving object in the forces related other under Accelerometer and are in the table a lot forces measure a and when it on a southern a to wait in a pump or a typical item or a Accelerometer consider either a number memes accelerometer and a typical accelerometer With a typical accelerometer consider a proof mass in a support either to a spring Pina or a dashboard in a control system You're a concept A pump or a typical Accelerometer another down to a proof mass supported by a spring and a dashboard for damping the vibrating proof Proof mass in a vibrating in a Damning a priority in a and on the Dashboard It on a typical Accelerometer in the diagram Instantaneous displacement Displacement in you see the Velocity Displacement divided by time and the channel can either be of T is equal to d y of T divided by DT and the rate of change of Velocity and a number of the Acceleration in the Alpha of T is equal to the Correction on the the either you know the dy of T divided by DT and on a total karate Alpha of T is equal to none and DV of T divided by DT and then I'm okay. I'm gonna D V of T divided by DT and I said D D square y of T divided by DT square and the market is that either D by DT of dy of T By DT and then I'm okay D square y of T divided by DT square on the item But a correction on the rain of the alpha of T is equal to D V of T divided by DT in the correct here number a dynamic force on the rain and on a Voice on the rain of the and the moving object in a voice on the rain of the mass into acceleration And I'm gonna put a dynamic force on the rain in Newton's lab. I'm gonna give up T is equal to Mass Acceleration alpha of T Mass of the moving soul F of T is equal to M into alpha of T Conventional Miniature If you want to design a small accelerometer, you need a coil spring and a dashboard You can't use a dashboard for damage Then you need an alternative Coil spring, dashboard and proof mass You need an alternative to design a micro accelerometer There are two types of micro accelerometers One is cantilever beam micro accelerometer Second is balanced force micro accelerometer Cantilever beam micro accelerometer Cantilever beam accelerometer Balanced force micro accelerometer This figure is a cantilever beam accelerometer This has coil spring, proof mass, dashboard, etc Cantilever beam is the function of coil spring The surrounding viscous fluid is the dashing port for damping of the proof mass The moment of proof mass is carried out by the attached piezo resistor Piezo resistor acts as the proof mass Micro accelerometer is a micro accelerometer It has all the details of a normal accelerometer Cantilever beam is the function of coil spring Viscous fluid is the dashing port for damping of the proof mass Proof mass is the piezo resistor Let's see the balanced force micro accelerometer The concept of balanced force micro accelerometer is used in airbag deployment sensors in automobiles The plate beam acts as the proof mass 2N tethers acts as the spring The surrounding air acts as the dashing port The moment of proof mass is carried out by the measuring the change of capacitances between the pair of electrodes The moment of proof mass is carried out by measuring the change of capacitances between the pair of electrodes This is all about micro accelerometer Today we learned about application of micro agitators We discussed micro grippers, micro motors, micro pump, micro valve and micro accelerometer Hope everyone understood See you in the next lecture Thank you
