A COVID-19 sensor developed at Johns Hopkins University could revolutionize virus testing by adding accuracy and speed to a process that frustrated many during the pandemic. In a new study published ...

An electrochemical sensor developed at Oregon State University holds promise for making food quality testing faster, more accurate, more environmentally friendly, and less expensive. The novel sensor, ...

The wheels of a moving vehicle can move at different speeds, with some turning faster than others. This can cause a loss of steering control and compromise safety on the road. To mitigate this, speed ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...
