摘要: An electric field sensor comprising: a substrate having a hole; a shielding electrode and a sensing electrode, disposed in the hole of the substrate; a piezoelectric bar having one end connected to the center of the shielding electrode, the other end fixed on the substrate. Present invention provides several electric field sensors, which have the same feature of utilizing electrodes interleaving vibration to modulate external electric field. They have IC-compatible operation voltage and small volume.
