Accurate Testing of Flexible Hybrid Electronics Using Tension-Free Systems

Flexible devices are coming. Early failures could be disastrous for a new product. It is imperative that the devices withstand the mechanical stresses induced by their use, i.e., being worn on a human body, vehicle displays, bendable components. etc. Various mechanical stresses (bending, torsion, tension, compression, folding, etc.) will occur on wearable devices because of human movement. Testing to determine the strength of the devices will be a necessary part of product design. Different types of stress must be included in the testing to ensure durability of the product. We have found that tension-free testing is an excellent way to get consistent results. In the case of a typical torsion test, one must think about the stresses that will happen to devices. Isolation of forces is enhanced with tension-free testing. For more than five years, tension-free modular equipment has been developed by YUASA SYSTEM to allow testing that yields more accurate results than traditional methods. The tension-free method allows testing that meets the specifications of international standards, and we are seeking to collaborate with academia and corporations to gather and evaluate data that shows the differences. Some developers are thinking that endurance testing will be at the end of the development process, but the winners will be conducting their endurance tests in the early stages of development so that durability is designed into the product.

 

Speaker's Biography

I am  Naotsugu Ando, chief designer at R&D department of YUASA SYSTEM.

I am designing mechanical structures to reproduce various phenomenon on the sample with our endurance testing systems since 2010.
