3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

A three-legged stick-slip piezoelectric actuator inspired by haystack unloading device and it’s driving method

Results in Engineering
Currently, the driving waveforms of existing stick-slip piezoelectric actuators are mostly sawtooth or modified sawtooth waveforms. The steep descending edge of the sawtooth waveform causes vibrations and backward motion, significantly limiting their ...

Reliability of a MEMS Actuator Improved by Spring Corner Designs and Reshaped Driving Waveforms

Sensors, 2007
In this paper, we report spring corner designs and driving waveforms to improve the reliability for a MEMS (Micro-Electro-Mechanical System) actuator. In order to prevent the stiction problems, no stopper or damping absorber is adopted.
