“…Therefore, transient electronics have potentially a broad field of applications, for example, temporally implantable devices, biosensors and sensors, energy storage devices, and triboelectric nanogenerator . To date, transient electronics have mainly relied on biodegradable or water‐soluble polymers as substrates, for example, polylactic acid, polycaprolactone, silk, poly(lactic‐ co ‐glycolic acid), natural wax, cellulose derivatives, poly(vinyl alcohol) (PVA), and polyvinylpyrrolidone . The choice of the substrate material is mostly dependent on the external trigger for disintegration.…”

Transient electronics, arising electronic devices with dissolvable or degradable features on demand, is still at an early stage of development due to the limited choices of materials and strategies. Herein, a facile fabrication method for transient circuits by the combination of room-temperature liquid metals (RTLMs) as the electronic circuit and water-soluble poly(vinyl alcohol) (PVA) as the packaging material is reported. The as-made transient circuits exhibit remarkable durability and stable electric performance upon bending and twisting, while possessing short transience times, owing to the excellent solubility of PVA substrates and the intrinsic flexibility of RTLM patterns. Moreover, the RTLM-based transient circuit shows an extremely high recycling efficiency, up to 96% of the employed RTLM can be recovered. As such, the economic and environmental viability of transient electronics increases substantially. To validate this concept, the surface patterning of RTLMs with complicated shapes is demonstrated, and a transient antenna is subsequently applied for passive near-field communication tag and a transient capacitive touch sensor. The application of the RTLM-based transient circuit for sequentially turning off an array of light-emitting-diode lamps is also demonstrated. The present RTLM-based PVA-encapsulated circuits substantially expand the scope of transient electronics toward flexible and recyclable transient systems.

Materials, Processes, and Facile Manufacturing for Bioresorbable Electronics: A Review

et al. 2018

View full text Add to dashboard Cite

Bioresorbable electronics refer to a new class of advanced electronics that can completely dissolve or disintegrate with environmentally and biologically benign byproducts in water and biofluids. They have provided a solution to the growing electronic waste problem with applications in temporary usage of electronics such as implantable devices and environmental sensors. Bioresorbable materials such as biodegradable polymers, dissolvable conductors, semiconductors, and dielectrics are extensively studied, enabling massive progress of bioresorbable electronic devices. Processing and patterning of these materials are predominantly relying on vacuum-based fabrication methods so far. However, for the purpose of commercialization, nonvacuum, low-cost, and facile manufacturing/printing approaches are the need of the hour. Bioresorbable electronic materials are generally more chemically reactive than conventional electronic materials, which require particular attention in developing the low-cost manufacturing processes in ambient environment. This review focuses on material reactivity, ink availability, printability, and process compatibility for facile manufacturing of bioresorbable electronics.

“…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

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.
