Abstract. A hypothesis is presented that allows one to explain the practically important property of the previously developed capacitive sensor of biological tissues blood supply, namely the increase in time of sensor measurements for living biological tissues and the absence of this effect for non-living biological tissues. It is based on the presence of rectifying properties in some potassium channels of cell membranes. The experimental part of the work to confirm the hypothesis was performed on 7 male white laboratory rats weighing 200-250 grams. An open phenomenon opens up the fundamental possibility of using a capacitive blood supply sensor in practical medicine to expressly indicate the viability of tissues of injured and sick people. Due to the miniaturization and autonomy properties of the capacitive sensor which is considered in the work, it could find applications in disaster medicine and emergency surgery for the urgent assessment of blood supply and tissue viability at the prehospital and hospital stages of emergency care.
Key words: biological tissue, blood supply, capacitive sensor, permittivity.
