Oscillating power generating element
UndeterminedDE102025147942A1Electrostatic generators/motorsParasitic capacitanceMechanical engineering
[Task] Provision of an oscillating power generating element in which it is possible to sufficiently reduce a parasitic capacitance that may occur in the oscillating power generating element and thereby increase the frequency band in which power generation is possible.[Solution] Oscillating current-generating element comprising stationary electrodes, which include a plurality of comb-shaped electrodes, movable electrodes, which include a plurality of comb-shaped electrodes that engage with the comb teeth of the stationary electrodes, and elastic support elements that ensure that the movable electrodes move relative to the stationary electrodes in the same plane in a certain direction, characterized in that, in a state in which at least one of either the stationary electrodes or the movable electrodes is electrically charged, the engagement length of the stationary electrodes and the movable electrodes and the deflection magnitude of the elastic support elements are equal, or the engagement length of the stationary electrodes and the movable electrodes is smaller than the deflection magnitude of the elastic support elements.

Electrostatic end effectors for manufacturing system robots
Disclosed herein are embodiments of electrostatic end effectors and methods of manufacturing the same. In one embodiment, the electrostatic end effector comprises a ceramic base, a first electrode layer coupled to the ceramic base, and a second electrode layer coupled to the ceramic base. The electrostatic end effector is configured to generate an electrostatic force on a substrate in response to a voltage applied to the first electrode. The electrostatic force on the substrate can increase the frictional force on the substrate, which can enable the end effector to accelerate at a faster rate than current technology without the substrate slipping on the end effector.

Precision drive and sense operation for microelectromechanical systems devices
PCT designated stageWO2026133304A1Television system detailsImpedence networksControl engineeringHemt circuits
A system includes a set of electrostatic actuators. Each electrostatic actuator of the set of electrostatic actuators includes a high-voltage side and a low-voltage side. The low-voltage side is configured to be driven by a time-varying voltage signal (TVVS). The system includes a set of drive-sense channels. A representative channel of the set of drive-sense channels includes a drive electrical link between (i) a corresponding drive circuit of a set of drive circuits and (ii) the high-voltage side of a corresponding electrostatic actuator of the set of electrostatic actuators. The representative channel is configured to carry, via the drive electrical link, a controllable drive voltage from the corresponding drive circuit to the high-voltage side of the corresponding electrostatic actuator. The representative channel includes a sense electrical link configured to carry a current generated by the TVVS to a sense-measurement circuit.
