A novel disposable band aid-sized wearable sensor has now been developed to monitor your minute-by-minute activity such as your pulse, eye blinks and even walking pace all using a cheap toilet tissue. The findings of this study are published in the journal of Advanced Materials Technologies. The sensor is light, flexible and inexpensive, with potential applications in healthcare and robotics.
‘The band aid-sized sensor can detect heartbeats, finger force, finger movements, eyeball movements and so much more. It has a variety of applications such as that of monitoring a person's gait and to inspect brain functions.’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.
For the research, the team used conventional paper towels, then doused them with carbon nanotube-laced water.
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.
