However, these sensors require bulky components for power or for interrogation that hinder miniaturization. We have proposed a wireless sensing method based in passive rectification of high frequency current bursts that flow through the tissues by volume conduction. Here we report the evaluation of a 0.98 mm-thick, passive, and flexible temperature sensor based on this method. The injectable microsensor obtained an accuracy of ±2.1%. This opens the possibility of continuous and in situ temperature sensing with minimal invasiveness.application/pdfeng© 2021 IEEE. Personal use of this material is permitted.
