Abstract

We present a novel tool for fast sensor or materials testing. A planar electrode structure on alumina substrate with internal heater allows four-wire impedance spectroscopy measurements. One can easily distinguish between conduction / relaxation mechanism resulting from the bulk material or the electrode interface. Investigations of YSZ thick films prove the applicability of the presented system.
