In situ monitoring of temperature and voltage in lithium-ion rechargeable batteries using flexible micro two-in-one sensors

Lee C.-Y., Lee S.J., Lee C.-Y., Lee S.J., Tang M-S, Chen P-C, Chang Y-M, Yuan Ze University, TW

Under overcharge conditions, the interior temperature of polymer lithium-ion rechargeable batteries will rapidly increase. Such batteries are adopted in electric vehicles that require rapid charging and discharging, and this process causes rapid heating, raising safety [...]

A Framework for Mask-Layout Synthesis Implementing a Level Set Method Simulator

Lee C.-Y., Antonsson E.K., California Institute of Technology, US

Recently, evolutionary methods have been developed to automate MEMS mask-layout synthesis [3]{[6]. These design synthesis methods are iterative searches in which each iteration consists of mask-layout modification, determination of etched shape via an arbitrary 3-D [...]

Self-Adapting Vertices for Mask-Layout Synthesis

Lee C.-Y., Antonsson E.K., California Institute of Technology, US

An efficient procedure for synthesizing MEMS mask-layouts for a desired 3-D shape is discussed. This method can greatly reduce the number of design and prototype iterations required to produce a desired device. The method is [...]

Surface Reconstruction of Etched Contours

Lee C.-Y., Antonsson E.K., California Institute of Technology, US

Previously, a computationally efficient and geometrically accurate etching simulation was developed to compute con-tours of constant depth at different time steps [1]. Experi-mental verification of this early work has been established [2]. However, contours are [...]
