Direct-Write Planar Microultracapacitors by Laser Engineering
We have successfully employed laser direct write and micromachining to fabricate high capacity hydrous ruthenium oxide (RuOxHy or RuO2 • xH2O) microultracapacitors. A laser direct-write process is used to deposit uniform pads of RuO2 • 0.5H2O in sulfuric acid under ambient temperature and atmospheric conditions. Ultraviolet laser micromachining is used to tailor the shape and size of the deposi...
متن کاملLi-ion microbatteries generated by a laser direct-write method
A laser-based direct-write process is demonstrated as a method to fabricate Li-ion microbatteries. The battery electrodes are made by the laser-induced forward transfer of inks of charge-storage materials (composites of carbon/binder and LiCoO2/carbon/binder) onto micromachined metal-foil current collectors to form 40–60 m thick electrodes with 16 mm2 (4 mm × 4 mm) footprints. Both half cells a...
متن کاملIsolated node engineering of neuronal systems using laser direct write.
Current limitations to the engineering of ex vivo and in vitro neural environments are hampering the ability to understand underlying neurophysiology. High levels of spatial specificity, reproducibility and viability have been previously reported using laser direct write (LDW) to print cells. However, despite the significant need no one has yet reported laser assisted printing of primary mammal...
متن کاملOptical Trap Assisted Nanoscale Laser Direct-Write Patterning
Laser direct-write patterning methods are traditionally limited by the diffraction limit to size scales several hundreds of nanometers at the minimum. In this work, we demonstrate a new method of laser based patterning that overcomes these limitations by taking advantage of near-field enhancement at the surface of dielectric microspheres. Polystyrene microspheres are trapped in CW Bessel beam l...
متن کاملFabrication Of Mesoscale Energy Storage Systems By Laser Direct-Write
Over the last two decades, there has been a trend towards the development of smaller and more autonomous electronic devices, yet the question of how to power these microdevices with correspondingly small power sources remains. To address this problem, we employ a laser forward-transfer process in combination with ultraviolet laser micromachining, to fabricate mesoscale electrochemical power sou...
