Matrix microsensor information scanning

The problem with tactile sensing in the modern computer systems isn´t decided yet. Concrete tactile sensor versions are developed for a specific application. In some papers, we represented the research results for the suggested ferropiezoelectric tactile matrix microsensor. It is applicable for 2D image obtaining. The basic advantage is the high resolution at small number of the sensor pins and direct digital coding of the information. The problems via the increased resolution (Todorova and Mladenov, 2002; Todorova and Mladenov, 2004) impose using of new type electronic interface (Todorova and Mladenov, 2004). In this paper the operating principle and the electronic circuit structure of the suggested interface are considered.
