Pressure-sensitive electronic ‘skin’

click to enlargeA thin pressure sensor under development by a team at Stanford University has the potential to impact robotics, health tech devices, smartwatches and prosthetics. A transistor made of a flexible polymer semiconductor is actually more sensitive than skin, detecting temperature, pressure and humidity, and works even when curved. At a pulse point, it not only detected pulse but also “a second, weaker wave of blood being bounced back from the extremities, and a third wave that can provide a measurement of the stiffness of the artery. Stiff arteries can be a sign of damage from diabetes, or cholesterol buildup.” LiveScience. Published in Nature Communications in May and somehow winding up in the NY Post this week.
