A KAIST team 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 and shows potential for the detection of subtle human motions and the real-time monitoring of body postures for healthcare applications. The study “Wearable Strain sensors Using Light Transmittance Change of Carbon Nanotube-Embedded Elastomers with Microcracks” was published in Applied Materials & Interfaces in ...
