Ferroelectric biochip

A biochip comprising at least one coupling arrangement configured for electrical stimulation of biological material or electrical measurement of the biological material, the biochip comprising:

• a support structure arranged at and/or in the coupling arrangement;
• and
• a layer, a layer surface of which is arranged at the coupling arrangement, and an opposite layer surface of which forms a coupling surface for electrical stimulation of the biological material and/or for electrical measurement on the biological material;
• wherein the layer has ferroelectric properties;
• wherein the biochip is configured for simultaneous measurement as well as stimulation and to this end comprises a plurality of mutually separated coupling surfaces with different associated coupling arrangements;
• wherein the biochip comprises at least a first coupling surface with an associated first coupling arrangement which is configured for an electrical measurement on the biological material and comprises a field-effect transistor and/or electrical conductors for a connection to a field-effect transistor and
• at least one further, second coupling area with an associated second coupling arrangement, which comprises an electrically conductive electrode layer adjacent to the layer and is configured for electrical stimulation of the biological material.
