Wireless power distribution is demonstrated using an infrared laser and an area‐enhanced Si‐doped HfO 2 pyroelectric receiver, where Brayton‐style thermodynamic cycles are employed to significantly enhance the efficiency compared to simple resistive harvesting. More details can be found in article number 1900515 by Clemens Mart and co‐workers.
