According to the researchers, the inclusion in the materiala small number of silver atoms leads to the formation of weakly conductive nano-sized filaments. The electrical circuit formed by such filaments quickly opens with the release of heat. If a large number of silver particles are included in the material, then the electrical circuit formed by such particles is stable.

Scientists have used this feature of silver indeveloping his device, depending on the strength of stimulation, a different amount of silver particles is fed into the sensor. In case of prolonged exposure to a weak stimulus, the electrical current in the system decreases over time, mimicking adaptation. However, when exposed to a strong stimulus, strong electrical signals are generated that cause pain.
“The significance of this study lies in the fact thatthat in addition to the ability of electronic devices to mimic pain, they can easily adapt to weak stimuli that are harmless to the human body,” notes Chong-Yun Kang.
Scientists believe that their development will help in the creation of artificial skin, internal organs and humanoid robots.
