Wireless radiation sensor

摘要

Disclosed is a sensor for detecting radiation. The sensor includes a ferromagnetic metal and a radiation sensitive material coupled to the ferromagnetic metal. The radiation sensitive material is operable to change a tensile stress of the ferromagnetic metal upon exposure to radiation. The radiation is detected based on changes in the magnetic switching characteristics of the ferromagnetic metal caused by the changes in the tensile stress.

1. A radiation sensor comprising:
a ferromagnetic metal; and a radiation sensitive material indirectly coupled to the ferromagnetic metal via a molecular recognition reagent directly coupled to the ferromagnetic metal, the radiation sensitive material operable to emit a gas upon exposure to radiation such that the molecular recognition reagent changes a tensile stress of the ferromagnetic metal upon exposure to the emitted gas from the radiation sensitive material.
