Our goal for this year is to get the device in as many vehicles as possible so we can save as many lives as possible.” “Both of us have experienced driving while tired, and we thought a sensor would be a great tool to help decrease the number of accidents caused by impaired driving,” Alex says. The two decided to team up and develop a technology to be used in cars. But WISe can communicate to the car to slow down the bag’s deployment by notifying the vehicle that a passenger doesn’t meet the minimum requirements. Algorithms clean up the data, generating a clear radar image for biometrics and communicating with the vehicle and the infotainment system if it suspects an issue with the driver or a passenger. When the waves are reflected back to the sensor, the received echo allows WISe to “see” the small movements and gather data about the person’s health status.

WISe takes the driver’s readings daily to discern what the person’s normal range is and displays the data on the car’s infotainment screen. WISe detects changes in the reflected signal’s phase—the relationship between radio signals that share the same space and frequency—to read the micromovements and vital signs. WISe is the first in-market millimeter-wave wireless sensor used for that purpose in the automotive industry, Qi says. WISe sends out signals with wavelengths short enough to measure the tiny adjustments in a person’s body from breathing and pulse. The WISe system measures the driver’s vital signs including heart rate and breathing to detect fatigue and possible medical emergencies.
