Researchers in US have created an 'electronic skin' that can store and transmit data about a person's movements, receive diagnostic information and release drugs into skin.

The technology could aid patients with movement disorders such as Parkinson's disease or epilepsy, they claimed. What we are talking here is a "sticky patch containing a device roughly four centimetres long, two cm wide and 0.003 millimetres thick", said Nanshu Lu, a mechanical engineer at University of Texas in Austin.

Researchers constructed the device by layering a package of stretchable nanomaterials sensors that detect temperature and motion, resistive RAM for data storage, micro heaters and drugs onto a material that mimics the softness and flexibility of the skin.

"Although some commercially available components, such as lithium batteries and radio-frequency identification tags can do this work, they are too rigid for the soft-as-skin brand of electronic device," Lu explained.

The findings were published in the journal Nature Nanotechnology1.
