An Implantable Sensor and a Wearable Detector

原文（中国語）

Broadly speaking, embodiments of the present techniques provide an implantable sensor for detecting physiological signals within a patient, and a wearable detector for receiving sensed data from the implantable sensor. The implantable sensor comprises at least one transistor for sensing the physiological signal, at least one light source to emit light of a predetermined intensity and frequency in response to the sensed physiological signal, and a powering mechanism to power the transistor(s) and the light source(s). Advantageously, the implantable sensor can be made small enough so that it is injectable into a patient using a fine needle rather than requiring extensive surgery.
