Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in South Korea have developed a thin, flexible, transparent hierarchical nanocomposite (HNC) film that can be used to create a high-performance, transparent nanoforce touch sensor.
The researchers say the sensor features high sensitivity, transparency, bending insensitivity, and manufacturability.
The device's sensing electrodes are on the same plane as the neutral plane, which allows the touch sensor to operate even when bent to the radius of a ballpoint pen, with no change in performance.
Said KAIST's Jae-Young Yoo, "We successfully developed an industrial-grade force touch sensor by using a simple structure and fabrication process. We expect it to be widely used in user touch interfaces and wearable devices."
