New Functional MR Thin-Film Device.

Development of Flexible Electrochromic Device with Thin Film Configuration

High-resolution thin-film device to sense texture by touch.

Touch (or tactile) sensors are gaining renewed interest as the level of sophistication in the application of minimum invasive surgery and humanoid robots increases. The spatial resolution of current large-area (greater than 1 cm(2)) tactile sensor lags by more than an order of magnitude compared with the human finger. By using metal and semiconducting nanoparticles, a approximately 100-nm-thick...

Programmable polymer thin film and non-volatile memory device.

Building on the success of organic electronic devices, such as light-emitting diodes and field-effect transistors, procedures for fabricating non-volatile organic memory devices are now being explored. Here, we demonstrate a novel organic memory device fabricated by solution processing. Programmable electrical bistability was observed in a device made from a polystyrene film containing gold nan...

Thin film nano solar cells--from device optimization to upscaling.

Stainless steel based dye solar cells have been upscaled from small, laboratory size test cells of 0.32 cm2 active area to 6 cm x 6 cm "mini-modules" with active areas ca. 15 cm2. Stainless steel works as the photoelectrode substrate whilst the counter electrode is prepared on indium-doped tin oxide coated polyethyleneterephtalate or polyethylenenaphtalate plastic foil (fluorine-doped tin oxide...

Vibration Energy Harvesting with Pzt Thin Film Micro Device

A micro power generator for harvesting vibration energy by means of a piezoelectric laminated cantilever with inertial mass was designed, fabricated, and characterized. The device was micro machined from a silicon-on-insulator structure coated with a 2μm thick piezoelectric PZT thin film. Interdigitated electrodes (IDE) were applied to achieve higher voltages. A piezoelectric coupling constant ...
