Optical Wi-Fi allows for ultrafast underwater communications

EPFL spin-off Hydromea has developed a miniature optical modem that can operate down to 6,000 meters below the ocean's surface. It is sensitive enough to collect data at very high speeds from sources more than 50 meters away.

A system for the nonreciprocal transmission of microwave acoustic waves

Acoustic waves have been found to be highly versatile and promising carriers of information between chip-based electronic devices. This characteristic is ideal for the development of a number of electronic components, including ...


The power of light for internet of underwater things

A system that can concurrently transmit light and energy to underwater energy devices is under development at KAUST. Self-powered internet of underwater things (IoUT) that harvest energy and decode information transferred ...


The robot that grips without touching

ETH Pioneer Fellow Marcel Schuck is developing a robotic gripper that can manipulate small and fragile objects without touching them. The technology is based on sound waves.


A battery-free sensor for underwater exploration

To investigate the vastly unexplored oceans covering most our planet, researchers aim to build a submerged network of interconnected sensors that send data to the surface—an underwater "internet of things." But how to supply ...
