Results in brief
Bioresorbable Self-powered Implantable Device
The Marie Curie Individual Fellowship entitled ‘Bioresorbable Self-powered Implantable Device’ (BIOIMD) trained the talented research, Dr. Sujoy Kumar Ghosh, in the highly relevant scientific and technological fields of piezoelectric energy harvesting and biomedical devices. Novel implantable medical devices (IMDs) allow one to perform continuous detection and analysis of physiological parameters as well as of disease evolution inside the human body. Hence, they are very important in the broad framework of human health care, diagnostics, prevention of diseases, and monitoring of therapies. However, a few challenges remain to be addressed, such as the need of IMDs to be supplied with continuous power. This is the key issue being addressed by the BIOIMD project. To overcome problems related with implantable batteries, including limited lifetime and surgical positioning, the pursued strategy is scavenging energy from biomechanical sources using biocompatible and ultimately bioresorbable piezoelectric devices. To this aim, BIOIMD was designed by three interlinked workpackages and focused on the implementation and development of effective arrays of nanopillars based on bio-polymers to be used as (i) biodegradable energy harvester and (ii) implantable biomedical device.

Project objective
The interaction between medicine and technology allows the development of new implantable medical devices (IMDs) to detect or monitor diseases inside the human body. The key challenge is to supply continuous power to the IMDs. Conventional strategy to use the implantable battery suffers from limited lifetime, maintenance problem, hazardous chemicals and requirement of periodic replacement through surgery which eventually increase patient health risk. In this context, scavenging electricity from biomechanical energy sources using piezoelectric energy harvester is a smart strategy for realizing self-powered implantable bioelectronics, since it can harvest electric energy from inexhaustible slight motions of organs such as heart, lungs, and diaphragm. In this regard, the devices should be flexible and at the same time biodegradable to avoid invasive removal surgery that can damage directly interfaced tissues. Despite recent achievements in self-powered electronic devices, there is still a tremendous need to develop an efficient self-powered IMD which only relies on safe medical materials. In this context, the focus of the project is to develop high performance natural piezo-electric polymer based biodegradable IMD which can be absorbed by the body after certain period of time without any adhere toxicity. In addition, we will emphasize on material science, underlying concepts in mechanics and associated engineering strategies in device construction. The key design strategies for the piezoelectric device based self-powered IMD will adopt interdisciplinary approach from materials science (nanopillar configurations), chemistry (organic bio-polymers processing), applied physics (modeling, theoretical simulation), engineering (IMD circuit design) and biology (device implantation). This collective concept suggests a promising future across a range of fields, particularly in biomedical engineering, nanoneurotechnology and next-generation wireless implantable biomedical device.
