Researched and developed biomimetic sensor based on biomimetic smart material and the semiconductor (Si). Prepared biomimetic sensor compared with their biological counterparts have a number of technological advantages – availability, easeness of  use and long working life. Its high activity sensitive and  to determine steadiness permit the concentrations in aqueous solution of H₂O₂ to 10^-6 mas.% and  ethyl alcohol  to 10^-4 mas.%.
