MEMS: The Sensory Nervous System for Embodied AI Robots
SmartBot, Volume 1, Issue 3, September 2025.Embodied AI represents a shift of intelligence from virtual to physical realms, calling for efficient and multimodal perceptual capabilities. This review illustrates how Micro‐Electro‐Mechanical Systems (MEMS) offer miniaturized, low‐power sensors such as those for ranging, inertia, touch, sound and smell, which serve as robotic “sensory organs”.

Ultrasound fundamentals and their clinical implications for interventional cytopathologists
Cytopathology, Volume 36, Issue 4, Page 356-374, July 2025.Interventional cytopathologists need to know about ultrasound physics and instrumentation to produce an image that faithfully recreates the lesion discovered by the sonographer and diagnosed by the radiologist. A deep quantitative understanding of physics is not required.

Volumetric real-time imaging using a CMUT ring array [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012 A ring array provides a very suitable geometry for forward-looking volumetric intracardiac and intravascular ultrasound imaging. We fabricated an annular 64-element capacitive micromachined ultrasonic transducer (CMUT) array featuring a 10-MHz operating frequency and a 1.27-mm outer radius.
