Metal halide perovskites are of increasing use in applications beyond conventional photovoltaics, from flexible solar cells for wearable devices to field-effect transistors for unconventional computing.
High-tech industries power the modern digital world, but their supply chains are particularly vulnerable to geopolitical and economic disruption. Urgent action is needed to improve supply-chain resilience.
Substantial improvements in computing energy efficiency, by up to ten orders of magnitude, will be required to solve major computing problems — such as planetary-scale weather modelling, real-time, brain-scale modelling and human evolutionary simulation — by the end of this century.
The capabilities of touchless user interfaces that recognize hand gestures are improving, but their place in the future of everyday electronics remains uncertain.
