Biochip for capacitive stimulation and/or detection of biological tissues.
The biochip has a carrier structure, at least one stimulation and/or
sensor device, which is arranged in or at the carrier structure, and at
least one dielectric layer, one layer area of which is arranged at the
stimulation and/or sensor device and the opposite layer area of which
forms a stimulation and/or sensor area for capacitive simulation and/or
detection of biological tissues, wherein the dielectric layer comprises
TiO.sub.2.
