stretchable electronics

The Laboratory for Soft Machines & Electronics (www.caogroup.org) at the MSU has one postdoc associate opening in the areas of soft materials and machines. The research work is expected to be highly multi-disciplinary, and the specific topics includes: Smart materials and structures, Soft robotics, Artificial skins; Energy harvesters, Wearable Electronics, Machine Learning, etc. This position is available immediately.

Skin is the largest organ of the human body, and it offers a diagnostic interface rich with vital biological signals from the inner organs, blood vessels, muscles, and dermis/epidermis. Soft, flexible, and stretchable electronic devices provide a novel platform to interface with soft tissues for robotic feedback and control, regenerative medicine, and continuous health monitoring.

Dear colleagues,

You are cordially invited to submit abstract(s) to Symposium D-12 Mechanics, Materials, and Manufacture of Flexible and Stretchable Electronics at the 2016 SES meeting to be held at the University of Maryland-College Park during October 2-5, 2016. Abstracts can not be more than 350 words and are due on Wednesday, June 15, 2016.

Recent Progress in Curvilinear Electronics and Mechanics

1. Introduction

The rapid and efficient development of soft active materials requires readily available, compact testing equipment. We propose a desktop-sized, cost-efficient, and open source radial stretching system as an alternative to commercially available biaxial and uniaxial stretching devices. It allows for doubling the diameter of an elastomer membrane while measuring the applied force. Our development enables significant cost reduction (<300 €) and increase the availability of equibiaxial deformation measurements for scientific material analysis.

Introduction

In today's (May 2) issue of Nature, we report a recent achievement in applying mechanics principles of stretchable electronics and optics to create biologically inspired artificial compound eye cameras. It was also highlighted in the Nature News & Views, "Optical devices: Seeing the world through an insect's eyes".

Dear all,

I would like to recommand a paper on "Postbuckling analysis and its application to stretchable electronics"。 Please find enclosed paper which is published on Journal of the Mechanics and Physics of Solids Vol. 60 (2012) 487–508.

We systematically investigated the interesting electric response of the aligned CNT ribbons under mechanical strain. We found that CNTs slide on a PDMS substrate under tension, but buckle under compression (releasing). Such an irreversible mechanical deformation is responsible for the observed irreversibility in the electric resistance upon the first stretching/releasing.

Abstract:

A review paper on stretchable electronics written by Professors John A. Rogers, Takao Someya, and Yonggang Huang was published in a recent issue of Science . This paper gives a nice summary on the recent advances in inorganic and organic stretchable electronics. Materials, structures and mechanics of these systems are discussed. Many attractive applications of stretchable electronics are introduced, such as stretchable silicon circuit, electronic eyeball camera, and flexible LED display.
