Researchers have developed a novel wearable strain sensor based on the modulation of optical transmittance of a carbon nanotube (CNT)-embedded elastomer. The sensor is capable of sensitive, stable, and continuous measurement of physical signals. This technology shows great potential for the detection of subtle human motions and the real-time monitoring of body postures for healthcare applications.
