Bio-electromechanical device capable to convert electrochemical potential energy stored in a both animal or plant cellular system to mechanical energy. This bio-electromechanical device has sizes varying in the order of microns, with maximum electric voltages near 100 mV, currents in the order of nA and associated power in the order of 10<SUP>-10</SUP> W. The device uses the membrane potential, and specifically the action potential activation of an excitable cell, to power an electromechanical circuit which comprises at least a resistance, a capacitor and a mechanical oscillator connected to one of the capacitor plates. The resulting system is a bio-electromechanical system capable of self-oscillations triggered by a limit cycle in which the oscillating mechanical element, having different possible constructions, is the member that produces mechanical energy. The latter component can directly drive a user micro-device. |
