Skin inspired electronics can be used for mobile health such as wireless sensor bands, cell phone and computer at doctor’s office, according to Prof. Zhenan Bao, Stanford University. She was delivering the inaugural lecture on day two of the ongoing 13th Global Electronics Summit in Santa Cruz, USA.
There is an example of the heart pulse measurement. Another related device is the full pulse wave for medical diagnostics such as blood pressure monitoring, detecting arrhythmia, heart defects and vascular diseases. In terms of temperature sensing, Stanford has developed a flexible body temperature sensor made of plastic.
There is chemical sensing as well. These are very stable and can be put in sea water. There are also electronics to mimic the body, such as the biodegradable OTFT. Another example is the transparent, stretchable pressure sensor. Finally, the other attribute of the human skin is self healing. Stanford University also developed the all-self-healing e-skin.
The e-skin concept ‘Super Skin’ has touch pressure sensors, chemical or biological sensors in air – electronic nose and liquid environments – electronic tongue, flexible strechable materials, biocompatible or biodegradable, self-powered — strechable solar cells and self healing.
