Passive sensor system with carbon nanotube components

Abstract:

A passive wireless sensor system is disclosed that includes components fabricated from carbon nanotube (CNT) structures. In some situations, the passive wireless sensor system includes a CNT structure sensor and an antenna that communicates wirelessly by altering an impedance of the antenna. The passive wireless sensor system includes a non-battery-powered energy storage device that harvests energy from carrier signals received at the antenna. The antenna and the energy storage device can be formed from CNT structures.
