Panasonic has created a stretchable insulating film, which can be used in flexible electronic devices of the future. The material can withstand stretching 2.5 times its original length, and then returns to its original shape. The Japanese manufacturer has also developed a transparent electrode and conductive paste.
A new insulating film material is able to stretch and return to its original shape, which is unusual with traditional flexible materials. The film can be folded in different ways and take the shape of the surface to which it is applied. This flexibility allows you to design almost without limits, that is to design a soft and stretchable electronic devices, well adaptable to different shapes, such as the body or clothes.
According to the publication Nikkei, in the core of the development of own technology company. The strength parameters of the new material make possible its repeated use. This is confirmed by tests conducted by Panasonic.
Ordinary conductive metal is destroyed by stretching or squeezing of the material to which it is applied. This limits the use of metallic wiring in complex printed circuit boards. Metal fatigue also contributes to its destruction under the influence of periodic dynamic loads.
Panasonic used an insulating film together with the transparent electrode and the conductive paste based on a core of silver.
