Remote detection of animate entities

A sensor device for detecting animate entity, the sensor device comprising:

• a housing;
• a first analog matching filter and a second analog matching filter, each of the first and second analog matching filters comprising:
• a first plate,
• a second plate coupled with the first plate and separated from the first plate via a spacer,
• a replicate matching material fixed to an inside surface of the first plate,
• a conductive plate or sheet fixed to an inside surface of the second plate, and
• an electrical circuit connecting the first plate to the conductive plate or sheet;
• an internal member that is configured to react to the opposite polarization pattern carried by the electrical circuit;
• and
• a switch coupled with the first and second analog matching filters, the switch selectively activating the first analog matching filter or the second analog matching filter, wherein the replicate matching material and the conductive plate or sheet in at least the first analog matching filter generates an opposite polarization pattern carried by the electrical circuit that is based on a polarization pattern of animate entity according to a spatial gradient of the animate entity local electric field distribution.
