Abstract: Owing to rapidly developing methods of minimally invasive surgery a new class of devices appeared. These devices are known as tactile sensors for remote palpation. They give a possibility to the surgeon not to enter into direct contact with the internal organs of the patient and obtain tactile data. The article presents the circuitry design of a silicon crystal matrix of piezoresistive pressure sensing elements MIPD-32 for tactile diagnostics devices. The crystal is manufactured by means of combination of MEMS and CMOS technologies. The research results of the characteristics of the crystals are shown.
