Novel Microsensor Design to Improve Data Collection From Hard-To-Monitor Environments

Case ID:


Wireless microsensors have enabled new ways to monitor our environment by allowing users to measure spaces previously off limits to research, such as toxic areas, vehicle components, or remote areas in the human body. Researchers, however, have been stymied by limited improvements in the quality of data and sensitivity of these devices stemming from challenges associated with the environments they operate in and the need for sensors with extremely small footprints.




Researchers at Detroit’s Wayne State University have developed a new telemetry approach of designing microsensors with enhanced sensitivity and resolution.  They are using isospectral parity-time-reciprocal scaling, or PTX symmetry, a "reader," paired with a passive microsensor, that receives highly sensitive radio frequencies in a miniaturized setup. The researchers were able to demonstrate this phenomenon in a telemetric microelectromechanical (MEMS)-based wireless pressure sensor system.

- Internet-of-Things (IoT) sensors

- Cyber-Physical Systems


Stage of Development:
