400W wireless charger tracks moving receiver with maximum efficiency

Multiple transmit coils can ease positional constraints in wireless charging systems, but it is not easy to optimise power transfer. Now Korean engineers have found an elegant way to do it, only measuring the reflected receiver impedance from each transmit coil and processing that to decide how much current each transmitter should deliver. “Our strategy breaks ...

Imec to demo application of photolith to organic semiconductors

Later this week, Imec is showing how photolithography can be used to pattern organic semiconductors and the cathode in an OLED-display stack which has the potential to eliminate the use of fine metal masks (FMM). The demonstration is important for display manufacturers as photolithography enables higher resolutions, or an increased transparency of the cathode, to ...
