Hearables Will Monitor Your Brain and Body to Augment Your Life

Devices tucked inside your ears will make technology more personal than ever before

The eyes, it’s been said, are windows to the soul. I’d argue that the real portals are the ears.

Consider that, at this very moment, a cacophony of biological conversations is blasting through dime-size patches of skin just inside and outside the openings to your ear canals. There, blood is coursing through your veins, its pressure rising and falling as you react to stress and excitement, its levels of oxygen changing in response to the air around you and the way your body is using the air you breathe. Here we can also detect the electrical signals that zip through the cortex as it responds to the sensory information around us. And in that patch of skin itself, changing electrical conductivity signals moments of anticipation and emotional intensity.

Computing With Chemicals Makes Faster, Leaner AI

Battery-inspired artificial synapses are gaining ground

This analog electrochemical memory (ECRAM) array provides a prototype for artificial synapses in AI training.

How far away could an artificial brain be? Perhaps a very long way off still, but a working analogue to the essential element of the brain’s networks, the synapse, appears closer at hand now.

That’s because a device that draws inspiration from batteries now appears surprisingly well suited to run artificial neural networks. Called electrochemical RAM (ECRAM), it is giving traditional transistor-based AI an unexpected run for its money—and is quickly moving toward the head of the pack in the race to develop the perfect artificial synapse. Researchers recently reported a string of advances at this week’s IEEE International Electron Device Meeting (IEDM 2022) and elsewhere, including ECRAM devices that use less energy, hold memory longer, and take up less space.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
