Professor Shinji Takeoka of Waseda University and his colleagues have collaborated with an Italian research institute to develop an electronic nano-adhesive plaster that can be attached to the skin to read bioelectric signals.It can be attached to the skin without using an adhesive, and is thought to contribute to the development of next-generation wearable devices.

 Wearable devices that are worn on the body to read various biological information have become important devices in the medical and sports fields.In addition, by connecting to devices such as smartphones, even ordinary people can measure and manage heart rate and activity while exercising, and the number of users is increasing.On the other hand, there is still room for improvement, such as the fact that some devices may interfere with exercise.

 The group has developed medical nano-adhesive plasters that have high adhesion to the skin and organs.By combining this technology with the robotics technology of the Italian group, we have developed an electronic nano-adhesive plaster that incorporates an electric circuit into the nano-adhesive plaster.Since it fits gently on the skin surface, it can be worn comfortably and can read bioelectric signals.Furthermore, since the damage when peeling off is minimized, it is expected to be widely applied to the health care of infants, the elderly, and people with disabilities in addition to the exercise measurement of athletes.In addition, since it is possible to mass-produce roll-shaped materials, it is also a big attraction that the production cost can be kept low compared to conventional wearable devices.

 Electronic nano-adhesive plasters have the potential to greatly develop wearable devices, and can also be expected to be applied to artificial hands / legs and wearable robots.With these in mind, we will proceed with research to implement elaborate circuits.
