Panasonic Develops Stretchable Resin Film for Stretchable Electronics


Reading time ( words)

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

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 to desired manners of folding and to 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 resin film offers the following features developed on the basis of the Company's proprietary stretchable resin technology.

1. Soft and stretchable insulating film material that comes with excellent elasticity

  • Tensile elongation: x 2.5 or more

2. 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

3. Additional development of a stretchable transparent electrode material and conductive paste along with the insulating material

My View from CES 2021: Day 1

01/12/2021 | Dan Feinberg, Technology Editor, I-Connect007
What a difference a year makes. One year ago, those of us who cover and attend CES were going from one press conference to the next; this year, we are at home going from link to link. Confusing and challenging, yes, but there are some advantages: no masks, only five steps to get to a restroom, being able to have three of four events or more displaying on your screens at the same time and being able to download press kits as needed. So far, many new devices are being introduced, but of course, they are all online, so you wonder if some of them really exist or are truly operational as yet.

CES 2021: Just How Different Will It Be?

01/11/2021 | Dan Feinberg, I-Connect007
CES 2021 starts today and this year there is no need for an overpriced hotel room in Vegas, no long lines to get a taxi or board a bus, and no crowded exhibit halls (one good thing this year). On the other hand, you must decide ahead of time what you want to see and make a reservation or appointment if you wish to have time and access assured.

CES 2020: The Intelligence of Things

01/06/2020 | Nolan Johnson, I-Connect007
Show week for CES 2020 starts well ahead of the actual exhibition dates because it is huge. The organizers of CES state that there are more than 4,400 exhibiting companies and nearly three million net square feet of exhibit space. On the floor, you can find 307 of the 2018 Fortune Global 500 companies. Over the week, I-Connect007 Editors Dan Feinberg and Nolan Johnson will bring you some of the most interesting news, products, and announcements from 5G to IoT, semiconductor developments, autonomous vehicle technology, interconnect, fabrication materials, and much more.
