Transient soft bioelectronics are capable of forming conformal contacts with curvilinear surfaces of biological host tissues and organs. Such systems are often subject to continuous static and dynamic loads from the biological host. In this article, we present investigation of electronic attributes of transient soft bioelectronic circuits subjected to mechanical force and influence of substrate's transiency on the transiency of the whole device; also, characterize and quantify loss of functionality in triggered devices. Variations in the electrical conductivity of circuits as a function of applied mechanical load was used as a means to deduce electronic characteristics under stress. The experimental results suggest that there exists a correlation between electronic properties of circuits and applied mechanical strain; no clear correlation was, however, observed between electronic properties of circuits and frequency of the applied dynamic load. Control over transiency rate of identical circuits utilizing the transiency characteristics of the poly(vinyl alcohol)l-based substrates is also studied and demonstrated.

“…These considerations motivate research into forms of electronics that can degrade naturally into the environment to harmless end products. Such technology is also of interest for other, unique classes of applications, ranging from biodegradable, temporary electronic implants to hardware secure data systems and unrecoverable, field-deployed devices (9)(10)(11)(12). Sometimes referred to collectively as transient electronics, these types of devices can be constructed by using designer materials, such as specially formulated polymers or natural products (13)(14)(15)(16), or clever combinations of established materials, well-aligned to existing infrastructure (e.g., device designs, circuit topologies, manufacturing capabilities) in conventional, nontransient electronics (17)(18)(19).…”

Foundry-based routes to transient silicon electronic devices have the potential to serve as the manufacturing basis for "green" electronic devices, biodegradable implants, hardware secure data storage systems, and unrecoverable remote devices. This article introduces materials and processing approaches that enable state-of-theart silicon complementary metal-oxide-semiconductor (CMOS) foundries to be leveraged for high-performance, water-soluble forms of electronics. The key elements are (i) collections of biodegradable electronic materials (e.g., silicon, tungsten, silicon nitride, silicon dioxide) and device architectures that are compatible with manufacturing procedures currently used in the integrated circuit industry, (ii) release schemes and transfer printing methods for integration of multiple ultrathin components formed in this way onto biodegradable polymer substrates, and (iii) planarization and metallization techniques to yield interconnected and fully functional systems. Various CMOS devices and circuit elements created in this fashion and detailed measurements of their electrical characteristics highlight the capabilities. Accelerated dissolution studies in aqueous environments reveal the chemical kinetics associated with the underlying transient behaviors. The results demonstrate the technical feasibility for using foundry-based routes to sophisticated forms of transient electronic devices, with functional capabilities and cost structures that could support diverse applications in the biomedical, military, industrial, and consumer industries.soft electronics | biodegradable electronics | transfer printing | undercut etching | hydrolysis S emiconductor technology is increasingly essential to nearly all aspects of modern society, with projections of market sizes that will exceed $7 trillion in 2017, equivalent to 10% of the world's gross domestic product (1-4). The rapid and accelerating pace of innovation in this area leads to increases in the frequency with which consumers upgrade their devices, thereby contributing to the production of >50 million tons of electronic waste (e-waste) each year (5, 6). Furthermore, the anticipated emergence of electronics for internet-of-things applications, along with the continued proliferation of radio frequency (RF) identification tags and other high-volume electronic goods, create daunting challenges with the management of this e-waste (7, 8). These considerations motivate research into forms of electronics that can degrade naturally into the environment to harmless end products. Such technology is also of interest for other, unique classes of applications, ranging from biodegradable, temporary electronic implants to hardware secure data systems and unrecoverable, field-deployed devices (9-12).

“…[1][2][3][4][5][6] Like traditional devices, transient devices should have a solid structure and maintain reliable high-performance operation over a long lifespan. However, the advantage over traditional devices is the transience that enables the device to degrade in a controlled manner once an external trigger commences.…”

Transient battery is a new type of technology that allows the battery to disappear by an external trigger at any time. In this work, we successfully demonstrated the first transient rechargeable batteries based on dissoluble electrodes including V2O5 as the cathode and lithium metal as the anode as well as a biodegradable separator and battery encasement (PVP and sodium alginate, respectively). All the components are robust in a traditional lithium-ion battery (LIB) organic electrolyte and disappear in water completely within minutes due to triggered cascade reactions. With a simple cut-and-stack method, we designed a fully transient device with an area of 0.5 cm by 1 cm and total energy of 0.1 J. A shadow-mask technique was used to demonstrate the miniature device, which is compatible with transient electronics manufacturing. The materials, fabrication methods, and integration strategy discussed will be of interest for future developments in transient, self-powered electronics. The demonstration of a miniature Li battery shows the feasibility toward system integration for all transient electronics.
