In situ monitoring of biomedical parameters
with implantable sensors can provide information to trigger
interventional or therapeutic actions. 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

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.
