Tissue paper sensors show promise for health care, leisure, robotics — ScienceDaily

University of Washington engineers have turned tissue paper — much like rest room tissue — into a brand new sort of wearable sensor that may detect a pulse, a blink of a watch and different human motion. The sensor is gentle, versatile and cheap, with potential purposes in health care, leisure and robotics.

The expertise, described in a paper printed in January within the journal Advanced Materials Technologies, reveals that by tearing tissue paper that is loaded with nanocomposites and breaking the paper’s fibers, the paper acts as a sensor. It can detect a heartbeat, finger drive, finger motion, eyeball motion and extra, mentioned Jae-Hyun Chung, a UW affiliate professor of mechanical engineering and senior creator of the analysis.

“The major innovation is a disposable wearable sensor made with cheap tissue paper,” mentioned Chung. “When we break the specimen, it will work as a sensor.”

These small, Band Aid-sized sensors may have a wide range of purposes in varied fields. For instance, monitoring an individual’s gait or the motion of their eyes can be utilized to examine mind perform or a sport participant’s actions. The sensor may observe how a special-needs youngster walks in a house check, sparing the kid the necessity for hospital visits. Or the sensors might be utilized in occupational remedy for seniors.

“They can use these sensors and after one-time use, they can be thrown away,” mentioned Chung.

In their analysis, the scientists used paper much like rest room tissue. The paper — nothing greater than typical paper towels — is then doused with carbon nanotube-laced water. Carbon nanotubes are tiny supplies that create electrical conductivity. Each piece of tissue paper has each horizontal and vertical fibers, so when the paper is torn, the course of the tear informs the sensor of what is occurred. To hint eye motion, they’re hooked up to an individual’s studying glasses.

For now, the work has been contained to a laboratory, and researchers are hoping to discover a appropriate industrial use. A provisional patent was filed in December 2017.
