Cricket Inspired High Efficiency MEMS Speakers
Proceedings, 2017 We report on the realization of a biomimetic MEMS speaker inspired by field crickets. This speaker is at least five times thinner and four times more efficient than the current dynamic speakers used in portable electronics.

Electrowetting-Based Actuation of Liquid Droplets for Micro Transportation Systems
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 This paper describes the electrowetting-on-dielectric (EWOD) actuation of liquid droplets for transportation of micromechanical parts. As dimensions of mechanical parts decrease, surface tension and electrostatic force become dominant compared to gravity

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
