Abstract :

Biological systems are mechanically soft, with complex, 3D curvilinear shapes; modern electronic devices are rigid, with simple, 2D layouts.   Technologies that eliminate this profound mismatch in physical properties create opportunities for devices that can intimately integrate with the body, for diagnostic, therapeutic or surgical function with important, unique capabilities in biomedical research and clinical healthcare.  Over the last decade, a convergence of new concepts in mechanical engineering, materials science, electrical engineering and advanced manufacturing has led to the emergence of diverse, novel classes of 'biocompatible' electronic platforms.  This talk describes materials and design approaches for devices that can harvest and store energy to support the operation of such systems.  Examples range from flexible piezoelectric mechanical energy harvesters, implantable and bioresorbable solar cells and compact, bio-compatible batteries.  Use of these approaches in skin-integrated and implanted electronic devices will be presented.

Keywords: Wearable electronics; bioelectronics; batteries; energy harvesting
