First Review of Conductive Electrets for Low-Power Electronics

D. D. L. Chung    

Resumen

This is the first review of conductive electrets (unpoled carbons and metals), which provide a new avenue for low-power electronics. The electret provides low DC voltage (µV) while allowing low DC current (µA) to pass through. Ohm?s Law is obeyed. The voltage scales with the inter-electrode distance. Series connection of multiple electret components provides a series voltage that equals the sum of the voltages of the components if there is no bending at the connection between the components. Otherwise, the series voltage is below the sum. Bending within the component also diminishes the voltage because of the polarization continuity decrease. The electret originates from the interaction of a tiny fraction of the carriers with the atoms. This interaction results in the charge in the electret. Dividing the electret charge by the electret voltage V? provides the electret-based capacitance C?, which is higher than the permittivity-based capacitance (conventional) by a large number of orders of magnitude. The C? governs the electret energy (1/2 C?V?2) and electret discharge time constant (RC?, where R = resistance), as shown for metals. The discharge time is promoted by a larger inter-electrode distance. The electret discharges occur upon short-circuiting and charge back upon subsequent opencircuiting. The discharge or charge of the electret amounts to the discharge or charge of C?.
