Researchers develop tiny sensor for measuring subtle pressure changes inside the body: Advanced polymer optical sensor is designed to be implanted for long-term health monitoring

摘要

Researchers have developed an extremely sensitive miniaturized optical fiber sensor that could one day be used to measure small pressure changes in the body. "Our new pressure sensor was designed for medical applications and overcomes many of the issues of using silica-based fibers," said research team leader Hwa-Yaw Tarn from The Hong Kong Polytechnic University. "It is sensitive enough to measure pressure inside lungs while breathing, which changes by just a few kilopascals."
