Smart tattoo

Researchers at the University of Toronto have invented sensors that are embedded in a thin, flexible plate with a smiling face. Temporary tattoo hides medical sensors that can determine the pH level of the skin, which causes changes in the metabolic stress.

The difference is that the eyes of the smiling faces are the electrodes, and the ears - contacts, which can be connected a measuring pribor.

This figure schematically shows a process of screen printing, with which the sensors are applied to ordinary paper for temporary tattoos Using the manufacture tattoo different sensitive materials, it is also possible to determine the content and other components of sweat, such as sodium, potassium and magnesium, each of which is of interest for researchers working in the field of medicine and cosmetology.
