Prof. Canek Fuentes-Hernandez sees a great potential to use high-performance soft and stretchable photodetectors to enable pulse oximeters, like the one he is holding in his hand, to become more ergonomic and to consume less power. Credit: Canek Fuentes-Hernandez
Semiconductors are moving away from rigid substrates, which are cut or formed into thin discs or wafers, to more flexible plastic material and even paper thanks to new material and fabrication discoveries. The trend toward more flexible substrates has led to fabrication of numerous devices, from light-emitting diodes to solar cells and transistors.
Georgia Tech researchers have created a material that …
