Takao Someya at the University of Tokyo has developed a hypoallergenic, inflammation free, wearable e-skin health sensor that can be worn comfortably for a week. Somaya believes that this technology is the basis for truly long term, continuous health monitoring.
The electrode is based on nanoscale meshes containing a water-soluble polymer, polyvinyl alcohol and gold. A small amount of water is required to dissolve the PVA and attach the sensor to the skin.
Mechanical durability was tested by repeated bending and stretching (more than10,000 times) of a conductor attached to the forefinger of 20 people.
EMG recordings with the new sensor were as accurate as those using conventional electrodes.
