1. A system for witness integrity sensing comprising:
a plurality of sensors;
a hotspot transceiver configured to transmit a point-to-point radiofrequency energy signal, wherein the point-to-point radiofrequency energy signal is a non-steerable transmission beam; and
a sensor platform including:
an antenna configured to receive the radiofrequency energy signal,
an energy harvesting circuit coupled to the antenna configured to convert the radiofrequency energy signal to charge for powering the sensor platform, and
a sensor multiplexor, coupled to each of the plurality of sensors via a respective plurality of wires, wherein the sensor multiplexor is configured to collect sensed data from the plurality of sensors via the respective plurality of wires, and wherein each of the plurality of sensors is remote from the sensor platform.
