Abstract:
We demonstrate a tetherless, sub-millimeter implantable temperature sensing system employing ultrasonic powering and ultrasonic backscatter modulation assembled using commercially available components. We have demonstrated two sizes of sensors based on available components with volumes of 1.45 mm3 and 0.118 mm3. Individual sensors are able to resolve ±0.5 °C changes in temperature, suitable for medical diagnostic and monitoring purposes. Our goal is to solve a long-standing issue: chronically and tetherlessly monitoring deep tissue temperature.
