Flexible optical touch sensor simultaneously pinpoints pressure strength and location
WASHINGTON — Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of pressure with high sensitivity and stability. The advance in tactile sensing paves the way for next-generation robotic touch interfaces, advanced medical diagnostics and highly responsive wearable electronics.
“Unlike conventional optical tactile sensors, which tend to have a single input-output path, our sensor design achieves multiple optical channels by embedding polymer ...
