“…Transient electronics have a wide range of potential applications including those in healthcare, biomedical devices, environmental sensing/monitoring, green electronics, military and homeland security, to name a few examples. In the very recent years, researchers have developed a wide range of transient electronic devices capable of performing a variety of functions and responsive to a variety of triggering mechanisms including exposure to light, heat or solvent (often aqueous) . What is common among all these reported transient devices is the need for an external power source.…”

Transient Li‐ion batteries based on polymeric constituents are presented, exhibiting a twofold increase in the potential and approximately three orders of magnitude faster transiency rate compared to other transient systems reported in the literature. The battery takes advantage of a close variation of the active materials used in conventional Li‐ion batteries and can achieve and maintain a potential of >2.5 V. All materials are deposited form polymer‐based emulsions and the transiency is achieved through a hybrid approach of redispersion of insoluble, and dissolution of soluble components in approximately 30 min. The presented proof of concept has paramount potentials in military and hardware security applications. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2016, 54, 2021–2027

“…What is common among all these reported transient devices is the need for an external power source. The power is either supplied by inducting coils from a very close distance, or from external power supplies . To realize autonomous transient electronic devices, similar to conventional ones, a transient battery is essential.…”

“…Low-ceiling temperature polymers, which can be kinetically stabilized at room temperature by end-capping or cyclization of polymer chain and depolymerized by backbone bond cleavage under external stimuli, serve as great candidates for transient materials. [5,12,15] Transient power sources including both energy storage devices and energy harvesters, however, are indispensable for a fully transient electronic system. Diesendruck et al realized a mechanochemically triggered autonomic remodeling system using high molecular weight PPHA that can go through the depolymerization-repolymerization cycle similar to biological tissues.…”

operation. [5] They have found potential applications as medical diagnostic and therapeutic devices that can resorb into the body, environmental sensors that do not require recovery after data collection, and consumer devices that can be easily disposed without hazards. [6] The potential feature of disappearance with minimal or non-traceable remains also enables transient electronics to find opportunities in privacy or security applications where stealth is required or reverse engineering needs to be avoided. The transience property is largely attributed to the triggerable degradation of device substrates and encapsulation, which are typically made of a group of materials called transient polymers. Depending on constituting material, the transience can be achieved either through material dissolution or depolymerization. Pioneering efforts on transient electronics focused on solution dissolution of polymer matrix. Bioresorbable polymers such as silk, polycaprolactone, poly(glycolic acid), and poly(L-lactide-co-glycolide), were used as substrates, [7][8][9] and biocompatible, implantable devices such as transistor, [1] ring oscillators, [10] and energy harvesters, [11] have been demonstrated. The lifetime of such devices is controlled by the dissolution rate of the materials in the surrounding aqueous solution, making them unsuitable for non-biological applications. Transient electronics that disintegrate via material dissolution or depolymerization under certain stimuli have great potential in biomedical and military applications. The triboelectric nanogenerator (TENG), an emerging mechanical energy harvesting technology with great flexibility in material choices, is promising in offering transient power sources. Previously reported transient energy harvesters using biodegradable polymers require solutionbased degradation and have limited applications in non-biological scenarios. A short time span, sunlight-triggered degradable TENG is developed. The main substrate includes an acid-sensitive poly(phthalaldehyde) (PPHA), a photoacid generator (PAG), and a photosensitizer (PS). Through photoinduced electron transfer, the ultraviolet radiation absorbed by the PS istransferred to the PAG to generate photoacids that trigger the depolymerization of PPHA. Transient TENG-based mechanical energy harvesters and touch/acoustic sensors are successfully demonstrated by embedding silver nanowires onto the PPHA-based films. The fabricated devices degrade rapidly under winter sunlight. The degradation rate can be further tuned via changing the ratio of photosensitive agents. This work not only broadens the applicability of TENG as transient power sources and sensors, but also extends the use of transient functional polymers toward advanced energy and sensing applications.

“…Bioresorbable components and biodegradable electronics would greatly benefit one from each other findings, both pursuing the same goal of developing high‐quality devices that operate for a prescribed time and then vanish under well‐defined conditions. In both cases, mechanisms for triggering and tuning the dissolution of these devices by using different physico‐chemical conditions, such as, acidic or basic solutions, light exposure, and low or high temperatures, are envisaged to provide a more accurate on‐demand control over dissolution.…”

Bioresorbable Materials on the Rise: From Electronic Components and Physical Sensors to In Vivo Monitoring Systems

2020

Over the last decade, scientists have dreamed about the development of a bioresorbable technology that exploits a new class of electrical, optical, and sensing components able to operate in physiological conditions for a prescribed time and then disappear, being made of materials that fully dissolve in vivo with biologically benign byproducts upon external stimulation. The final goal is to engineer these components into transient implantable systems that directly interact with organs, tissues, and biofluids in real‐time, retrieve clinical parameters, and provide therapeutic actions tailored to the disease and patient clinical evolution, and then biodegrade without the need for device‐retrieving surgery that may cause tissue lesion or infection. Here, the major results achieved in bioresorbable technology are critically reviewed, with a bottom‐up approach that starts from a rational analysis of dissolution chemistry and kinetics, and biocompatibility of bioresorbable materials, then moves to in vivo performance and stability of electrical and optical bioresorbable components, and eventually focuses on the integration of such components into bioresorbable systems for clinically relevant applications. Finally, the technology readiness levels (TRLs) achieved for the different bioresorbable devices and systems are assessed, hence the open challenges are analyzed and future directions for advancing the technology are envisaged.
