Physical vapor deposition (PVD) at an appropriate temperature has been shown to produce ultrastable glass by the mechanism of surface accelerated diffusion. Recently, high-entropy materials have been discovered to display slower atomic diffusion due to the multicomponent high-entropy effects. How this delayed atomic motion influences the formation and stability of PVD glass remains elusive.

The flexible sensor, with a fixed operating frequency of 13.56 MHz, contains a RFID IC and a sensor circuit that is fabricated on a flexible printed circuit board (FPCB) using a Micro-Electro-Mechanical-System (MEMS) process.
