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.

High-power CMUTs: design and experimental verification [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012 Capacitive micromachined ultrasonic transducers (CMUTs) have great potential to compete with piezoelectric transducers in high-power applications. As the output pressures increase, nonlinearity of CMUT must be reconsidered and optimization is required to reduce harmonic distortions. In this paper, we describe a design approach in which uncollapsed CMUT
