Sensor converts mechanical pressure to light signals

Facebook Twitter LinkedIn Email Comments
A new sensor device uses thousands of nanowires to convert mechanical pressure into light signals that can be captured and processed optically. Applications for the sensor could include biological imaging and microelectro-mechanical systems. The device also could provide a new approach for human-machine interfaces, as it has the potential to produce an artificial sense of touch as sensitive as that of human skin. “You can write with your pen, and the sensor will optically detect what you write at high resolution and with a very fast response rate,” said Zhong Lin Wang, a...Read full article
