Abstract
An apparatus comprising: a radiation sensor having one or more radiation sensors and an on-board power harvester.
Claims20
A device comprising:
- a radiation sensor comprising one or more radiation sensors;
- an on-board power harvester,
- wherein the power harvester converts radiofrequency energy into electrical energy,
- wherein the radiofrequency energy is adjustable,
- wherein the power harvester comprises a radiofrequency coil, and
- wherein the radiofrequency coil is adjustable to optimize an integration of radio frequency receiver coils and sensors into a fabric.
3 more elements
A device comprising:
- a radiation sensor array comprising one or more radiation sensors;
- and
- a power harvester, wherein the power harvester converts mechanical vibration energy into electrical energy,
- wherein the resonant excitation of the power harvester has a frequency range of 6-8 Hz,
- wherein each of the one or more radiation sensors is surrounded by a filter material to provide an optimal angular response to radiation detected by each of the one or more radiation sensors;
- and
- wherein the optimal angular response of each of the one or more radiation sensors is independent of the angle of incidence of the radiation detected by each of the one or more radiation sensors.
