ELECTRIC FIELD SENSOR

摘要

The invention is a detection system comprising inexpensive, miniaturized sensors (50, 410) for detecting electric field (E-field) disturbances. Such sensors (50, 410) are easily and covertly deployable and have low power consumption. The devices (450) may incorporate visual or audio alerts and can include communications hardware (460) for transmitting data for further processing of the electrostatic events.
