This study demonstrates an energy-autonomous disposable supply-sensing biosensor platform for big-data-based healthcare application for the first time. The proposed supply-sensing biosensor platform is based on bio fuel cells and a 0.23-V 0.25-μm zero-Vth all-digital CMOS supply-controlled ring oscillator with a current-driven pulse-interval-modulated inductive-coupling transmitter. The all-digital...
A novel three-dimensional cell culture system was constructed with an array of cell panels (4×5) in a silicon chip, together with multi-channel drug containers. Human breast cancer (MCF-7) cells were embedded in a collagen–gel matrix and entrapped in a pyramidal-shaped silicon hole. Each cell panel can be isolated by a channel composed of a microfluid part and a reservoir. A cell panel was exposed...
Some of the recent topics on the use of microelectrodes for the materials characterization, especially for the materials in battery and sensor applications, were overviewed. Results were presented for conducting polymers and for battery active materials such as a graphitized carbon. The filament-type and the interdigitated-array-type microelectrodes were prepared, and used respectively for the particle-level...
