(PhysOrg.com) -- Harvesting mechanical energy from the environment and converting it into electrical energy has recently become a viable method for powering low-energy electronics, such as sensors and actuators. But the major ...
(PhysOrg.com) -- When a river flows into the sea, the location is more than just a haven for water commerce. The mixing of fresh and salt water that occurs at an estuary also dissipates energy, as the different salinity waters ...
MIT engineers have designed a "brain-on-a-chip," smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors—silicon-based components that mimic the information-transmitting ...
