“…Most conventional power supplies are not applicable to bioresorbable electronics because they typically rely on nonbioresorbable materials that are also toxic. The materials outlined in section and others can be used to fabricate power supplies that are fully bioresorbable, with operating parameters that are useful for practical applications in temporary biomedical implants. ,− This section reviews recent advances in bioresorbable power supplies including batteries, supercapacitors, and mechanical, radio frequency, and photovoltaic energy harvesters. They all have their own advantages and disadvantages.…”

Transient electronic systems represent an emerging class of technology that is defined by an ability to fully or partially dissolve, disintegrate, or otherwise disappear at controlled rates or triggered times through engineered chemical or physical processes after a required period of operation. This review highlights recent advances in materials chemistry that serve as the foundations for a subclass of transient electronics, bioresorbable electronics, that is characterized by an ability to resorb (or, equivalently, to absorb) in a biological environment. The primary use cases are in systems designed to insert into the human body, to provide sensing and/or therapeutic functions for timeframes aligned with natural biological processes. Mechanisms of bioresorption then harmlessly eliminate the devices, and their associated load on and risk to the patient, without the need of secondary removal surgeries. The core content focuses on the chemistry of the enabling electronic materials, spanning organic and inorganic compounds to hybrids and composites, along with their mechanisms of chemical reaction in biological environments. Following discussions highlight the use of these materials in bioresorbable electronic components, sensors, power supplies, and in integrated diagnostic and therapeutic systems formed using specialized methods for fabrication and assembly. A concluding section summarizes opportunities for future research.

“…These attributes form the basis for recent interest in using E-BSSs for powering wearable, [104,105] ingestible, [106] and implantable medical devices. [107] Selecting the appropriate materials for B-ESSs is crucial to ensure their safe and efficient operation. In general, B-ESSs consist of three functional components: i) anode (oxidizing electrode), ii) cathode (reducing electrode), and iii) ion exchange membrane or separator that can readily absorb ambient biofluids as electrolytes.…”

Recent developments in wearable and implanted devices have resulted in numerous, unprecedented capabilities that generate increasingly detailed information about a user's health or provide targeted therapy. However, options for powering such systems remain limited to conventional batteries which are large and have toxic components and as such are not suitable for close integration with the human body. This review provides an in‐depth overview of biofluid‐activated electrochemical energy devices, an emerging class of energy sources judiciously designed for biomedical applications. These unconventional energy devices are composed of biocompatible materials that harness the inherent chemistries of various biofluids to produce useable electrical energy. This article covers examples of such biofluid‐activated energy devices in the form of biofuel cells, batteries, and supercapacitors. Advances in materials, design engineering, and biotechnology that form the basis for high performance, biofluid‐activated energy devices are discussed. Innovations in hybrid manufacturing and heterogeneous integration of device components to maximize power output are also included. Finally, key challenges and future scope of this nascent field are provided.This article is protected by copyright. All rights reserved

“…Applications range from transient pollution monitors that do not require recovery to temporary implants that avoid the need for surgical removal. [1][2][3][4][5][6][7] Despite these unique and important opportunities, development of methods for mass manufacturing of such devices remains challenging. Traditional techniques used in the semiconductor industry, such as photolithography and wet etching, cannot be used without modification because many eco/bioresorbable Scheme 1.…”

Eco/bioresorbable electronics represent an emerging class of technology defined by an ability to dissolve or otherwise harmlessly disappear in environmental or biological surroundings after a period of stable operation. The resulting devices provide unique capabilities as temporary biomedical implants, environmental sensors, and related systems. Recent publications report schemes to overcome challenges in fabrication that follow from the low thermostability and/or high chemical reactivity of the eco/bioresorbable constituent materials. Here, this work reports the use of high‐speed sewing machines, as the basis for a high‐throughput manufacturing technique that addresses many requirements for these applications, without the need for high temperatures or reactive solvents. Results demonstrate that a range of eco/bioresorbable metal wires and polymer threads can be embroidered into complex, user‐defined conductive patterns on eco/bioresorbable substrates. Functional electronic components, such as stretchable interconnects and antennas are possible, along with fully integrated systems. Examples of the latter include wirelessly powered light‐emitting diodes, radiofrequency identification tags, and temporary cardiac pacemakers. These advances add to a growing range of options in high‐throughput, automated fabrication of eco/bioresorbable electronics.
