Thin film interfaces for micro electrochemical sensors

Planar microelectrochemical chips with thin film electrodes (Pt, Au, Ag/AgCl) of different shapes and arrangement (rectangular, circular, microdisk or interdigitated array), have been developed and fabricated. Microelectrochemical cell with closely vertically spaced electrodes (in sub tm-range) allows to exploit the effect of redox recycling and an increase of collection efficienty for a high current amplification. PC simulations of electro-mechanical properties of sl-BLM is useful tool for evaluation and prediction of BLM behaviour. Non-symmetric microelectrode arrays were designed and fabricated for electrical monitoring of human skin.
