This new wearable sensor is developed from tissue paper!
Scientists have used tissue paper to develop a Band-aid sized wearable sensor that can detect a pulse, a blink of an eye and other human movements. The sensor is light, flexible and inexpensive, with potential applications in health care, entertainment and robotics, researchers said. Researchers at University of Washington (UW) in the US, showed that by tearing tissue paper loaded with nanoparticles and breaking its fibres, the paper acts as a sensor.
It can detect a heartbeat, finger force, finger movement, eyeball movement and more, said Jae-Hyun Chung, associate professor at UW. “The major innovation is a disposable wearable sensor made with cheap tissue paper. When we break the specimen, it will work as a sensor,” said Chung, senior author of the research published in the journal Advanced Materials Technologies. These small, Band Aid-sized sensors could have a variety of applications in various fields.
For example, monitoring a person’s gait or the movement of their eyes can be used to inspect brain function or a game player’s actions. The sensor could track how a special-needs child walks in a home test, sparing the child the need for hospital visits. The sensors could also be used in occupational therapy for seniors. “They can …read more
