A small, flexible, wearable device has been created that can provide band-aid style human interface, monitoring health or environmental conditions. The human-machine interface (HMI) consists of a small strip of material that can attach to the skin.

The researchers from the University of Houston, USA, have created an ultra-thin electronic device that can collect health, diagnostic, and environment information, with the capacity for medical, personal and professional applications. Focusing on the comfort of the wearable device, an issue that researchers continue to improve.

The researchers explained how the HMI also has potential for uses with prosthetic skin – a robotic hand and other robotic devices – with a HMI. It is this interface that automatically collects and relays information back to the wearer. The researchers described the device in a paper published in Science Advances as ‘ultra-thin, mechanically imperceptible, and stretchable.’

The device was fabricated in a one-step process, which used a metal oxide semiconductor. This was made out of indiu zinc oxide, on a nano-sized polymer base.

‘Indeed, the device has potential for myriad uses not just in wearable technology for humans, but also for robotic applications, to provide a sensor on the surface of a robot that might be able to sense environmental or health conditions, said University of Houston Mechanical Engineering Professor, CunjiangYu.
