An important breakthrough essential for future flexible electronic devices — ScienceDaily

Field Effect Transistors (FET) are the core building blocks of modern electronics such as integrated circuits, computer CPUs and display backplanes. Organic Field Effect Transistors (OFETs), which use organic semiconductor as a channel for current flows, have the advantage of being flexible when compared with their inorganic counterparts like silicon.

OFETs, given their high sensitivity, mechanical flexibility, biocompatibility, property tunability and low-cost fabrication, are considered to have great potential in new applications in wearable electronics, conformal health monitoring sensors, and bendable displays etc. Imagine TV screens that can be rolled up; or smart wearable electronic devices and clothing worn close to the body to collect vital body signals for instant biofeedback; or mini-robots made of harmless organic materials working inside the body for diseases diagnosis, target drug transportations, mini-surgeries and other medications and treatments.

Until now, the main limitation on enhanced performance and mass production of OFETs lies in the

Do we need a smartphone with a sliding flexible screen?

Chinese manufacturer Xiaomi is working on a concept smartphone with a flexible screen that slides around the body of the device. At least, that looks to be the case from a patent application to the US Patent & Trademark Office (USPTO), which was registered in 2019, but only published and commented on a few days ago by the website WindowsUnited.
