Long-awaited magnetic interferometer might probe quantum gravity

03 Jun 2021

An Israeli-led collaboration has used atom-chip technology to build a magnet-based interferometer. The collaboration’s research, which combines aspects of two famous physics experiments from the past, reveals that the division of particle spins into two populations – as observed by Otto Stern and Walther Gerlach a century ago – involves pure quantum states. In the future, the new interferometer could be used to investigate quantum gravity as well as theories about a possible fifth force of nature.

WiFi signals used to power small electrical devices

 

WiFi signals used to power small electrical devices

02 Jun 2021



Ambient WiFi signals can be used to power small electrical devices such as LEDs, researchers in Singapore and Japan have shown. Hyunsoo Yang at the National University of Singapore and colleagues have developed a new way of connecting tiny microwave oscillators, allowing them to charge a capacitor that can then drive devices such as remote sensors. The research could also lead to the development of circuits that mimic the nervous system.


WiFi is ubiquitous in buildings and a growing number of public spaces, which are awash with 2.4 GHz microwaves used to exchange data. While this provides Internet access for the masses, large amounts of microwave energy goes to waste.
