Contactless vital-sign sensing has long been an attractive idea in healthcare, but 60 GHz radar is making it increasingly practical. The reason is rooted in physics: at this frequency, radar is sensitive enough to detect tiny body motions, including the chest displacement associated with breathing and even the much smaller vibrations caused by cardiac activity.

How do sensors help clinicians accurately find veins?
For routine procedures like blood analysis or for blood donations, a phlebotomist (the person who extracts the patient’s blood) applies a tourniquet to the upper arm to slow blood flow and then visually/physically locates a vein to insert the needle. While expertise varies, the best practitioners can be very precise and execute this procedure with […]
Accelerometers combine low power with four full scales
The MIS2DU12 MEMS accelerometer from STMicroelectronics is a 2.0mm x 2.0mm x 0.74mm device designed for wearable and implantable medical applications, combining 20nA power-down current with sub-1µA active mode operation. It integrates motion processing for free-fall, wake-up, tap detection and 6D or 4D orientation, along with an anti-alias filter and 128-level FIFO to reduce host […]

Sensors expert talks data acquisition, IoT, wearables, and AI
Sensors veteran Roger Grace spoke with EE World about his award, data acquisition, IoT, and the trouble with AI.
What new sensing approaches measure blood pressure?
Today’s cuff technique for measuring blood pressure (BP) goes back 100 years or so. While the sensors used to measure pressure have changed considerably, the inflate, deflate, and then-measure approach is quite similar. It has even been automated for home use. However, it is not a continuous measurement. In contrast, researchers are exploring several continuous, […]
