Wearable, Epidermal, and Implantable Thermal Radio Sensors

Researchers from The University of Rome II's Pervasive Electromagnetics Lab have been doing extensive research on new layouts of lightweight RFID antennas over textile or flexible substrates suitable to be attached onto the human body by means of plaster, cards, or embedded into garments. Slotted patch configurations enable the integration of motion sensors for the detection of weak body movements such as breath, but also periodic limb movements during the night or the first appearance of human stress. The cutting edge part of the research is the design of implantable RFID tags able to sense the evolution of some interior pathology such as the restenosis of an artery due to plaque formation and the arising of edemas.
