Chinese scientists have developed a sensor which could improve wearable device performance and accurately capture the subtle changes in people's expressions, according to the Science and Technology Daily Wednesday.
The sensor has very high response sensitivity in deformation conditions, said the newspaper. The scientists applied nano-materials to help enhance the sensor's flexibility.
The scientists from Nankai University in North China's Tianjin put the wearable sensor on different parts of the human body and captured tiny skin motions caused by pulse beats on the wrists.
Put on the throat, the sensor also monitored the sound of vocal cords and identified syllable changes, according to the newspaper.
The new sensor is not hard to produce, and the scientists are pushing forward the sensor's application in wearable devices for human health monitoring and movement detection. (Xinhua)
