Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to something far tinier than any transistor on a chip: single molecules that act ...

Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...

Abstract: Ultrasound is a widely used medical tool for noninvasive diagnosis, but its images often contain speckle noise which can lower their resolution and contrast-to-noise ratio. This can make it ...
