Panasonic develops stretchable substrate for stretchable and flexible electronics

A novel insulating substrate that can be stretched to 2.5 times the original size and then return to the original form

24 Dec 2015 | Editor

Panasonic Corp has recently announced that the company has developed a soft, flexible, and stretchable polymer substrate film using its proprietary stretchable substrate technology. The Company will also provide a transparent electrode material and conductive paste along with this insulating film.

According to the company this newly developed material is an insulating film material that stretches and returns to its original shape, a feature that is hard to find in conventional flexible materials.

It adapts varying free-form surfaces, substantially reducing existing design constraints. For example, it enables the construction of soft and stretchable electronic devices that are adaptable to a variety of forms, such as of clothing and the body. The newly developed material is deployable in a broad range of applications, from wearable devices to sensors, displays, and robots.

The stretchable substrate film offers the following features developed on the basis of the Company's proprietary stretchable resin technology.

  • Soft and stretchable insulating film material that comes with excellent elasticity
    • Tensile elongation: x 2.5 or more
  • Insulating film material capable of relaxing internal stresses arising from stretch, returning to its original shape, and withstanding repeated use
    • Percentage of stress relaxation: 60%
    • Recovery rate: 98% or more
  • Additional development of a stretchable transparent electrode material and conductive paste along with the insulating material
