1. A sensor for measuring the density of the biological fluid or the membrane resistance, for example human skin, non-invasive manner, characterized in that said sensor comprises a pulse generator, a temperature sensor and a transmitter for registering the pulse rate, depending on the biological fluid and the elasticity of the skin using the second Newtons law, F = m × a, where m is the mass provided by the fluid and a means of its acceleration in m / s, with a constant force F in Newtons (N), said transformation atel connected to the microprocessor, wherein the signal from the transmitter are converted to values of the relative density of said biological fluid sredy.2. Sensor according to Claim. 1, characterized in that the pulse generating device generates a pulse in the form of a mechanical impulse, vibrational force, the compressed pulse (second) air / liquid or sound volny.3. A sensor according to claim. 2, characterized in that the pulse generating device generates mechanical impuls.4. The sensor of Claim. 3, characterized in that the mechanical impulse generated by pneumatic or hydraulic impulsom.5. The sensor of Claim. 3, characterized in that the mechanical impulse generated by an electromagnet or a magnetostrictive material, wherein a pulse detection is recorded measuring coil or a variable capacitor, an LED, an accelerometer, a microphone, or any other sensitive receivers capable of controlling the effect of mechanical impulsa.6. Sensor according to claim. 5, characterized in that the mechanical pulse may be a single pulse sequences1. Датчик для измерения плотности биологической текучей среды или сопротивления мембраны, например кожи человека, неинвазивным способом, отличающийся тем, что упомянутый датчик содержит генератор импульсов, температурный датчик и преобразователь для регистрации скорости импульса в зависимости от биологической текучей среды и эластичности кожи с использованием второго закона Ньютона, F=m×a, где m означает массу представляемой
