Optimal Design of an Electrostatic Zipper Actuator

Brenner M.P., Lang J.H., Li J., Slocum A.H., Harvard University, US

We describe a method for predicting the optimal design of an electrostatic zipper actuator. The shape of the zipping beam and the electrode are optimized to maximize the applied force at a given stroke, while [...]

Magnetic Diffusion in Nonlinear Micro-Media: A Modified Finite-Difference Time-Domain Approach

Cros F., Allen M.G., Lang J.H., Massachusetts Institute of Technology, US

As flux densities and frequencies are raised to increase the performance of magnetic micro-actuators, micro-motors/generators, and micro-inductors, eddy currents and magnetic saturation start to limit the performance of these devices. In this paper, we present [...]

Modeling a High Power Density MEMS Magnetic Induction Machine

Köser H., Lang J.H., Massachusetts Institute of Technology, US

Most micro-scale electric and magnetic machines studied in the last decade lack the power density to support many practical applications. The magnetic induction machine reported here attempts to transcend this practicality barrier by offering power [...]
