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”.

Oxide Membranes from Bulk Micro‐Machining of SrTiO3 Substrates

Advanced Science, Volume 12, Issue 20, May 29, 2025.
Bulk‐micromachining of SrTiO3 substrates is employed to realize suspended structures made of epitaxial thin films of complex oxides such as trampoline resonators and sealed membranes with physical access from both sides. The fabrication protocol relies on wet chemical etching of SrTiO3 and uses (La,Sr)MnO3 as hard mask and device layers.
