Semiconductors that Stretch like Human Skin
From rigid substrates, semi conductors are moving towards new, flexible substrates which have led to the fabrication of numerous devices. The Georgia tech researchers have created a material that acts like a second skin layer and is up to 200% more stretchable than its original dimension without significantly losing its electric current. The researchers say the soft flexible photo detectors could enhance the utility of medical wearable sensors and implantable devices, among other applications.
The new semiconductor has properties similar to that of a rubber band. When conventional semi conductors break under strain, this new semiconductor is soft and stretchable and still has all the properties of a solid and rigid semiconductor. It is a super-soft material with the ability to generate and conduct electricity when exposed to light and he materials’ stretchability, especially given that a single layer was 1,000 times thinner than a human hair.
