Abstract
An electric field sensing device. The device includes a substrate, a sensing medium capable of experiencing a change in its electrical resistivity in response to an electric field, and electrodes for use in measuring the change. A method of making an electric field sensing device. The method includes depositing on a substrate a sensing medium capable of experiencing a change in its electrical resistivity in response to an electric field emitted by an object; and placing electrodes for use in measuring the change. An electric field sensing system. The system contains a plurality electric field sensing devices, an arrangement of the plurality sensing devices in a way to detect spatial variation of electric field emitted by objects in an environment; a computer system capable of monitoring the sensing devices, and detecting and comparing differences between the electrical fields sensed by individual devices.
