2017 IEEE 30th International Conference on Micro Electro Mechanical Systems (MEMS), 2017

This paper reports a new class of bulk PZT traveling wave ultrasonic micromotor fabricated from a single sheet of bulk PZT.

Studies on charging op polymer foils by triboelectricity

1985 5th International Symposium on Electrets (ISE 5), 1985

Triboelectricity, which is a kind of old and well known phenomena, has been used as a method of charging of polymer electrets(1). G.M. Sessler has shown that this method has not been used extensively, mostly because of lack of accurate reproducibility(2)R. Gerhard-Multhaupt mentioned in his recent paper that triboelectricity will probably be used as a simple and safe charging method(3). ...

CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005

Surge voltages with the rise time of the order of nano-seconds may cause partial discharge (PD) and result in the degradation of electrical insulation performance of the inverter-fed motor coils. We investigated the PD inception and degradation characteristics of twisted pair samples under surge voltage condition. Experimental results firstly revealed that there existed no obvious correlation between PD inception voltage ...

  • Annular ultrasonic micromotors fabricated from bulk PZT

    This paper reports a new class of bulk PZT traveling wave ultrasonic micromotor fabricated from a single sheet of bulk PZT. Actuation of electrode pairs in a differential quadrature configuration is enabled by use of transverse interdigitated electrodes to achieve bendingmode actuation of a stator ring, enabling a simple single-layer device design and enhancing the effective input voltage applied to the device. Using fabricated micromotor patterned by micro powder blasting, bi-directional rotary motion of 100 μm thick glass rotors is successfully demonstrated.

  • Studies on charging op polymer foils by triboelectricity

    Triboelectricity, which is a kind of old and well known phenomena, has been used as a method of charging of polymer electrets(1). G.M. Sessler has shown that this method has not been used extensively, mostly because of lack of accurate reproducibility(2)R. Gerhard-Multhaupt mentioned in his recent paper that triboelectricity will probably be used as a simple and safe charging method(3). We used "The Arrangement of Triboelectrometer and Auto-measuring Recorder" which was assembled by us to charge polymer such as LDPE, PS and teflon PEP foils. In this paper we discuss effects of some factors such as fimes of friction (n), normal pressure (p), frictional separate velocity (v) and relative humidity (RH) at RT. The results of our experiments have shown that charging electret by using suitable frictional materials is controllable, reproduceable and relatively uniform.

  • Partial discharge inception and degradation characteristics of inverter-fed motor sample under surge voltage condition

    Surge voltages with the rise time of the order of nano-seconds may cause partial discharge (PD) and result in the degradation of electrical insulation performance of the inverter-fed motor coils. We investigated the PD inception and degradation characteristics of twisted pair samples under surge voltage condition. Experimental results firstly revealed that there existed no obvious correlation between PD inception voltage (PDIV) and the rise time of surge voltage. Secondly, PD propagation and degradation characteristics were also investigated under the higher voltage application, and discussed in terms of charge behavior in air gap and on enamel surface. Finally, we obtained the dependence of time leading to BD on enamel coating thickness of the wire.

  • Traveling wave annular ultrasonic micromotors using bulk PZT

    This paper describes the development a novel traveling wave ultrasonic micromotor fabricated directly from low-cost and high-performance bulk piezoceramic PZT. We report a simpler approach to realizing traveling wave ultrasonic micromotors in which traveling waves are generated within a tethered annular stator microfabricated from a single sheet of bulk PZT. Actuation is achieved using interdigitated electrodes deposited on a single layer, enabling monolithic stators to be fabricated in a batch process from a single sheet of high quality bulk piezoceramic. The process requires only 2 photolithography steps, greatly simplifying design and manufacture while improving device performance and microfabrication costs.

  • Miniature gear reduction unit driven by a silicon electrostatic wobble motor

    This work illustrates and explores one possibility to link watch fine mechanics to silicon-based actuators. A small scale microreduction module, a pinion-gear train, coupled to an electrostatic wobble motor (calculated power figure about 1 /spl mu/W), is described. The motor parts are fabricated on silicon. Electrodeposition of nickel in a positive photoresist mould is used for the fabrication of the rotor (/spl phi/ 2 mm). This last is flexible to permit vertically- wobbling and is directly connected to an output shaft. Functional operation of this microreduction unit was successful and demonstrated the possibility to output torque from an electrostatic wobble motor. Measurements and observations of rotor elasticity and gears/axle characteristics:are presented and discussed in view of a possibly improved design.

  • DSP solution for wall-climber micro-robot control using TMS320LF2407 chip

    This paper describes the controller design for a wall-climber micro-robot using a DSP chip. Because of its high-speed performance, its support for multi-motor control and its low power consumption, the TMS320LF2407 DSP from Texas Instruments (TI) demonstrates itself as an ideal candidate of the single chip controller for the wall-climber micro-robot.

  • Electrostatic microactuators with integrated gear linkages for mechanical power transmission

    In this paper a surface micromachining process is presented which has been used to fabricate electrostatic microactuators that are interconnected with each other and linked to other movable microstructures by integrated gear linkages. The gear linkages consist of rotational and linear gear structures and the electrostatic microactuators include curved electrode actuators, comb drive actuators and axial gap wobble motors. The micromechanical structures are constructed from polysilicon. Silicon dioxide has been used as a sacrificial layer and silicon nitride was used for electrical insulation. A cyclohexane freeze drying technique is used to prevent problems with stiction. The actuators, loaded with various mechanisms, have been driven successfully by electrostatic actuation. The work is a first step towards mechanical power transmission in micromechanical systems.

    A selective chemical deposition (CVD) tungsten process is used to fabricate micromotors on a silicon substrate. The fabrication of the variable capacitance micromotors that have been produced using integrated-circuit processing is described. Both rotors and stators greater than 3 micrometers thick for these motors are formed using a high deposition rate, planar, and selective CVD tungsten process. Tungsten micromotors with rotor diameters of 100 micrometers and 60 micrometers have been fabricated with amorphous silicon rotor bearings.<<ETX>>

  • Ferrofluid-assisted levitation mechanism for micromotor applications

    This paper reports a highly simple and robust levitation method realized by ferrofluid for micromotor applications. A layer of ferrofluid is self- sustained on a permanent magnet to serve as liquid bearing that lifts the magnet up on the substrate, enabling low-friction movements of the magnet. A levitation height of ~500 μm is observed with a 1.6-mm-sized NdFeB magnet. The levitated magnet is electromagnetically driven by microfabricated planar coils to demonstrate a linear micromotor. The dynamic responses of the magnet slider are characterized to show its acceleration level of ~1 m/s2. The actuation force of 388 μN or greater is obtained. Using an array of the planar coils as the rail track, continuous actuations of the slider is achieved with the maximum velocity of 19 mm/s.
