A Stacked-type Electrostatic Actuator and Measurement of its Energy Efficiency
نویسندگان
چکیده
We have studied a stacked-type electrostatic actuator by folding two ribbon electrodes in an alternate configuration. The energy efficiency of this type of actuator was investigated using the thick-electrode-part actuator and triangle-shaped actuator. The maximum energy efficiency levels were 30–40% for the thick-electrode-part actuator and 40–50% for the triangle-shaped actuator.

LEAD-FREE BNKT PIEZOELECTRIC ACTUATOR
An actuator is a device that converts input energy into mechanical energy. According to various types of input energy, various actuators have been advanced. Displacement in the electromagnetic, hydraulic and pneumatic actuators achieve by moving a piston via electromagnetic force or pressure, however the piezoelectric actuator (piezoceramic plates) displace directly. Therefore, accuracy and spe...
متن کاملStability Analysis in Parametrically Excited Electrostatic Torsional Micro-actuators
This paper addresses the static and dynamic stabilities of a parametrically excited torsional micro-actuator. The system is composed of a rectangular micro-mirror symmetrically suspended between two electrodes and acted upon by a steady (dc ) while simultaneously superimposed to an (ac ) voltage. First, the stability of the system subjected to a quasi-statically applied (dc ) voltage is investi...
متن کاملProtonmotive force: development of electrostatic drivers for synthetic molecular motors.
Ferrocene has been investigated as a platform for developing protonmotive electrostatic drivers for molecular motors. When two 3-pyridine groups are substituted to the (rapidly rotating) cyclopentadienyl (Cp) rings of ferrocene, one on each Cp, it is shown that the (Cp) eclipsed, pi-stacked rotameric conformation is preferred both in solution and in the solid state. Upon quaternization of both ...
