"Shapeable microélectronics"

Abstract

Shape is a noticeable quantity in nature, which does not persist. Role of the shape can be gradually assessed integrating mechanical, chemical, electrical and magnetic functionalities in complex artificial systems. Development of new materials, technologies and circuits enabled a new class of microelectronic devices relying on variation of their 3D shapes, namely shapeable microelectronics. Similar to flexible and printable forms of microelectronics, novel functionalities with unmatched characteristics can be envisioned for shapeable microelectronic devices.
Being mechanically adaptable, this form of microelectronics allows a gentle automatic attachment and subsequent release of active micro-scale devices in in-vivo applications such as microsurgery where precise mechanical forces have to be exerted onto biological tissue. Equipped with integrated electronic the devices has a potential to interface biological tissues. Their self-assembly capability enables the high yield manufacture of three-dimensionally shaped devices that can rely on geometry and stress dependent physical effects in e.g. magnetic materials. Demonstrated arrays of giant magnetoimpedance sensors and cuff neuronal implants will provide a possibility to address physiological processes locally or distantly via magnetic and electric fields that are generated deep inside the organism, allowing unique real time health monitoring capabilities. An artificial shapeable skin built-up in a form of an active matrix with multiple sensory sites can be applied on a living organism enhancing existing and even enabling new perceptions. Finally, the signals in such a system will be processed and transferred back stimulating the tissue to form a close control loop, which is desired in novel artificial prosthesis.

Short bio

Dr. Karnaushenko obtained a M.Sc. degree in electrical engineering from Novosibirsk State Technical University in 2009. He has finished his Ph.D. at the Leibniz Institute for Solid State and Materials Research in Dresden (IFW Dresden) in 2016 obtaining the degree at the Technical University of Chemnitz, Germany. Currently, he continues his research at the IFW Dresden. His research interest includes flexible active electronics and magnetic sensors, stimuli responsive polymers and compact self-assembled tree-dimensional architectures.
