The rise of physical AI, intelligent systems that sense, interpret, and interact with the real world, is driving a fundamental shift in how electronics are designed. This includes audio devices. ‘Always-on’ sensors, voice interfaces, and ambient intelligence are no longer aspirational features; they are now baseline requirements for the next generation of consumer electronics. From […]

Why 60 GHz radar is finding a place in health monitoring
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. […]
Increased voltage levels and faster switching speeds influence on sensor placement and accuracy in EV systems
The advancements in the EV industry, such as WBG devices and 800 V systems, introduce specific technical challenges for sensor accuracy and physical placement. Higher operational voltages require more robust electromagnetic interference (EMI) filtering, while faster switching speeds generate high dv/dt and di/dt noise. This FAQ examines how these factors affect sensing integrity and provides […]

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 […]
AEC-Q200 NTC sensors support -55 °C to 175 °C
The NTCSP series from TDK Corporation is an expanded line of AEC Q200-compliant NTC thermistors rated for operation from -55 °C to +175 °C.

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 […]
Multi-turn encoders: expanding absolute position capability
Precise motion control often requires more than tracking position within a single rotation. Multi-turn encoders provide extended position feedback by counting complete revolutions in addition to angular displacement, enabling accurate monitoring in linear actuators, gear-driven systems, and high-travel rotary mechanisms. For engineers designing closed-loop control systems, understanding the tradeoffs between resolution, retention method, and system […]
