New York Feb 15 (IANS) Using cheap toilet tissue scientists have developed a novel disposable 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 healthcare and robotics.

Researchers in the journal Advanced Materials Technologies showed that by tearing a tissue paper that is loaded with nanocomposites 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 the University of Washington.

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

These small band aid-sized sensors could have a variety of applications such as monitoring a person s gait the movement of their eyes and to inspect brain function or a game player s actions.

The sensor could also track how a special-needs child walks in a home test as well as in occupational therapy for seniors.

"They can use these sensors and after one-time use they can be thrown away " Chung noted.

For the research the team used conventional paper towels then doused them with carbon nanotube-laced water.

Carbon nanotubes are tiny materials that create electrical conductivity. Each piece of tissue paper has both horizontal and vertical fibres so when the paper is torn the direction of the tear informs the sensor of what has happened.

To trace eye movement they are attached to a person s reading glasses.

For now the work has been contained to a laboratory and researchers are hoping to find a suitable commercial use.
