Electro-Mechanical Testing of Conductive Materials Used in Flexible Electronics

Electro-Mechanical Testing of Conductive Materials Used in Flexible Electronics

The use of flexible electronics has increased in recent years. In order to have robust and long lasting flexible displays and sensors, the combined electro-mechanical behavior needs to be assessed. The most common method to determine electrical and mechanical behavior of conductive thin films used in flexible electronics is the fragmentation test or uniaxial tensile straining of the film and su...

Mechanical Issues for Flexible Electronics

Electrical Impedance Spectroscopy for Electro-Mechanical Characterization of Conductive Fabrics

When we use a conductive fabric as a pressure sensor, it is necessary to quantitatively understand its electromechanical property related with the applied pressure. We investigated electromechanical properties of three different conductive fabrics using the electrical impedance spectroscopy (EIS). We found that their electrical impedance spectra depend not only on the electrical properties of t...

Electronic materials: buckling down for flexible electronics.

T he success of electronic paper, roll-up displays and many other potential applications of flexible electronics will depend on the availability of electronic materials that can be stretched, compressed and bent. Previous efforts to develop electronic materials that can be mechanically deformed without breaking have mainly focused on small organic molecules and polymers. Unfortunately, these ma...

A Flexible Electro-mechanical Design Information System

Design information systems are of increasing importance due to globalization of product development, increasing complexity of products (in terms of product variants and range of technologies employed) and increasing emphasis on improving product development efficiency (shortening times, reducing cost, increasing performance). Current design information systems are typically applicable in a limi...
