Sesame seed-sized radar senses movements a fraction of the width of a hair

Engineers at the University of California, Davis (UC Davis) have developed a new radar sensor that can pick up movements just 100th the width of a human hair. Better yet, the sensor itself is only the size of a sesame seed and is energy efficient.Conti… Continue reading Sesame seed-sized radar senses movements a fraction of the width of a hair

Brain-computer interfaces give two women their voices back

Losing the ability to speak after a brain injury or due to disease leaves a person unable to express their thoughts, feelings and ideas, and can be incredibly isolating. In two recently published studies, researchers demonstrated how combining brain im… Continue reading Brain-computer interfaces give two women their voices back

Pants made with electronic yarn could transmit exhaustion alerts

Most of us don’t really need to wear special pants that let us know when we’re exhausted; we’re good at figuring that out all on our own. However, when it comes to hardcore athletes, getting an alert when the body starts moving in a way that indicates … Continue reading Pants made with electronic yarn could transmit exhaustion alerts

MechSense 3D-prints wireless rotational sensors right into moving parts

It’s certainly handy to know how fast gears or wheels are spinning, but equipping them with external sensors can be awkward and may affect their performance. That’s why scientists have devised a method of 3D-printing wireless sensors right into the thi… Continue reading MechSense 3D-prints wireless rotational sensors right into moving parts
