Researchers at the Technical University of Madrid have come up with a new way to produce optical nanosensors that can be applied to uneven surfaces..

Their technology will make it possible to start mass production of skin nanosensors and widely introduce them into medical practice..

For example, to monitor body temperature, heart rate, changes in body position or physical activity level.

The technology lies in the fact that sensors are made from cheap aluminum films and polycarbonate coating in combination with ordinary adhesive tape.. An aluminum film only 100 nanometers thick has holes that are applied at a certain density. The number of holes on the film determines how well light will penetrate through it, and what characteristics the product will eventually have..

Below are some data from the report of the Spanish researchers.

“Flexible nanosensors allow us to track changing environmental characteristics and identify specific chemicals..

In addition, they change their color depending on the angle of illumination, which allows you to determine any changes in the shape of the surface on which the sensor was fixed.. The production of flexible nanosensors relies only on the production of familiar polycarbonate, which is used in CDs, as well as aluminum film and adhesive tape, which makes the procedure for gluing sensors simple and fast.. Simply put, flexible plates on adhesive tape are obtained..
