Abstract Scope |
Electrically conductive electrets (unpoled carbons and metals) are a new untapped source of low-power electrical energy. 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 gives 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 a component also diminishes the voltage, due to 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’ gives the electret-based capacitance C’. The discharge or charge of the electret amounts to the discharge or charge of C’. |
