"3D printed, detect a specific signal. This streamlined process is similar to how nerve endings detect and transmit signals. The specialization of the sensor enables it to quickly discern triggers without consuming a lot of energy or requiring supervision.... small, autonomous, low energy... ideal for applications that are hazardous or hard to reach, including locations embedded structure or within humans... blood-brain barrier organoids or ultrasound structural monitoring"
