TL;DR: In this article, an electrical dipole is connected in parallel with a piezo-electric insert and an electrical load, and a switch is closed for a duration that is less than mechanical stress variation time.

TL;DR: In this paper, an elementary micromachined digital electromagnetic actuator for microdisplacements is presented, which is composed of a permanent magnet placed in a silicon square cavity and can reach four discrete positions and can be switched by applying current pulses through wires placed below the cavity.

TL;DR: In this article, a micro-fabricated electrodynamic micro-speaker with an optimized silicon structure based on a very light but very stiff membrane is presented, where the electromagnetic motor is composed of a permanent ring magnet and of a mobile planar coil fixed on the top of the silicon membrane.

TL;DR: In this article, the authors proposed a reversible conversion of electric power capable of being connected between at least an input alternating voltage source and at least a load forming an output alternating current source, each input voltage source having a supply terminal and a neutral terminal.

TL;DR: The energy recovery module of the capsule comprises: a primary oscillating structure (60) subjected to an external low frequency cyclic loading, a secondary oscillation structure (70) comprising an elastic member (74) and adapted to freely vibrate in high frequency resonance; and an electrostatic structure (80) with a first electrode (82) coupled to the primary structure and a second electrode (84) coupling to the secondary structure as mentioned in this paper.
