A major challenge in self-powered wearable sensors for health care monitoring is distinguishing different signals when they occur at the same time. Researchers addressed this issue by uncovering a new ...

We propose an optical fiber tip probe pressure sensor based on Fabry-Pérot interferometer (FPI). This sensor is fabricated by splicing single-mode, multimode, and hollow-core fibers using arc ...

You have an FPGA circuit and you want the user to interact with your circuit by pushing a button. Clearly, you need a button, right? Not so fast! [Clifford Wolf] recently found a mysterious effect ...
