Scientists have come up with a tiny sensor that detects skin diseases
Scientists at Northwestern University, Illinois, have partnered with Hong Kong City University researchers to develop an electromechanical device to detect skin problems. A miniature device reads the degree of hardness of the skin using vibration.
In a person suffering from problems with the skin, the affected tissue has either a higher density, or, on the contrary, becomes thinner. The sensor reads such features. This will allow doctors to quickly identify the problem and prescribe the appropriate treatment.
The thickness of the sensor is 2.5 mm, the contact area is 2 by 2 cm. When the sensor is attached to the site of probable problems, alternating electrical impulses are sent to the skin through the coils. A vibration is created that directs the pressure into the tissue to a depth of 8 mm. As a result, the skin begins to deform. The force with which this occurs determines the degree of tensile stiffness.
By reading the indicators, the sensor transmits the information to the computer. The doctor, comparing the result of the study with certain parameters, determines what kind of skin disease the patient has.
At the moment, there are already systems that record changes in skin stiffness during stretching. But they are all large enough, and a specially trained person is needed to decipher the results.
If the developers manage to bring the device to the wide market, then it can be used both by doctors in clinics and by patients at home. If your skin needs special care, then you can buy face and body cream, as well as other body care products on our website in the section " Health and beauty".
