  Internally Generated Voltage Signals in Self-Oscillating Casimir–Electrostatic Mems with Conserved Energy Dynamics
  Author(s): Patrick Sangouard*
  
  We present a theoretical model of a Casimir-effect micro/nano-electromechanical system exhibiting self-oscillating behavior and internally generated voltage signals, strictly within the framework of Emmy Noether's theorem. The device consists of a fixed piezoelectric beam mechanically coupled to a movable electrode subjected to Casimir attraction at nanometer distances. The mechanical deformation of the beam induces piezoelectric charges that drive a synchronized electrostatic switching sequence. This sequence involves complementary MOS switches connected to a Coulomb electrode and a passive RLC circuit. The operating principle relies on a redistribution of electrical charges induced by the deformation, transiently generating electrostatic forces that oppose Casimir attraction. This controlled force imbalance induces rapid mechanical relaxation, leading to a stable self-oscillatin.. Read More»
