According to the site EE Times, researchers from the Technical University of Eindhoven have developed a wireless temperature sensor powered by the energy of electromagnetic millimeter waves used including in communications.
Dimensions of the sensor is only two square millimeters, its weight is 1.6 milligrams, and the device is used for the manufacture of 65nm CMOS. It includes an antenna which not only serves to exchange data with a special router, but extracts energy electromagnetic radiation. The current version of the interaction radius of the sensor and the router is only 2.5 centimeters, but within a year the researchers intend to extend the range of up to one meter.
This technology can also be used in other types of sensors: light, motion, moisture. Cost of tiny devices are expected to be at the level of 20 cents per share. Related Products :
