Materials and noncoplanar mesh designs for integrated circuits with linear elastic responses to extreme mechanical deformations Export

@article{citeulike:3747083, abstract = {10.1073/pnas.0807476105 Electronic systems that offer elastic mechanical responses to high-strain deformations are of growing interest because of their ability to enable new biomedical devices and other applications whose requirements are impossible to satisfy with conventional wafer-based technologies or even with those that offer simple bendability.
