“…These processes allow for the production of devices with multimaterial layers and are compatible with the manufacture of flexible sensors, microlens, and supercapacitors. [ 330,331 ] However, they involve many manufacturing steps, which inhibits their use for rapid throughput applications. They are also costly and are susceptible to the occurrence of imprinting defects like the presence of air bubbles and ink sticking to the mold instead of being transferred.…”

New and innovative applications in the field of electronics are rapidly emerging. Such applications often require flexible or stretchable substrates, lightweight and transparent materials, and design freedom. This paper offers a complete overview concerning flexible electronics manufacturing, focusing on the materials and technologies that have been recently developed. This combination of materials and technologies aims to fuel a fast, economical, and environmentally sustainable transition from the conventional to the novel and highly customizable electronics. Organic conductors, semiconductors, and dielectrics have recently gathered lots of attention since they are compatible with printing technologies, and can be easily spread over large and flexible substrates. These printing technologies are usually simple and fast procedures, which rely on low‐cost and recycle‐friendly materials, intended for large‐scale fabrication. Overall, even though organic large‐area electronics manufacturing is still in its early stages of development, it is a field with tremendous potential that holds promise to revolutionize the way products are designed, developed, and processed from the factory premises to the consumers’ hands. Besides, this technology is highly versatile and can be applied to a large array of sectors such as automotive, medical, home design, industrial, agricultural, among others.

“…PGS degrades by 17% after 60 days in phosphate-buffered saline (PBS) solution, and the degradation rate can be tailored. A pressure sensor array designed for cardiovascular monitoring was developed by sandwiching a PGS elastic dielectric layer between two iron–magnesium electrode layers ( Figure 7 a) [ 116 , 124 ]. The pressure response stays stable, even at a bending radius down to 27 mm.…”

The rapid development of micro/nanofabrication technologies to engineer a variety of materials has enabled new types of bioelectronics for health monitoring and disease diagnostics. In this review, we summarize widely used electronic materials in recent low-profile implantable systems, including traditional metals and semiconductors, soft polymers, biodegradable metals, and organic materials. Silicon-based compounds have represented the traditional materials in medical devices, due to the fully established fabrication processes. Examples include miniaturized sensors for monitoring intraocular pressure and blood pressure, which are designed in an ultra-thin diaphragm to react with the applied pressure. These sensors are integrated into rigid circuits and multiple modules; this brings challenges regarding the fundamental material’s property mismatch with the targeted human tissues, which are intrinsically soft. Therefore, many polymeric materials have been investigated for hybrid integration with well-characterized functional materials such as silicon membranes and metal interconnects, which enable soft implantable bioelectronics. The most recent trend in implantable systems uses transient materials that naturally dissolve in body fluid after a programmed lifetime. Such biodegradable metallic materials are advantageous in the design of electronics due to their proven electrical properties. Collectively, this review delivers the development history of materials in implantable devices, while introducing new bioelectronics based on bioresorbable materials with multiple functionalities.

“…The in vitro degradation rate of PGS sheets crosslinked at 125°C in a culture medium is 0.6-0.9 mm month -1 , while the in vivo degradation rate is in the range of 0.2-1.5 mm month -1 [271] . PGS has been used as a dielectric for fully resorbable pressure sensors based on parallel plate capacitors, and has shown stable performance in a PBS buffer solution for more than 7 weeks [272] .…”

“…Bioresorbable sensors are essential components for bioresorbable electronics, and have been realized in formats such as biopotential electrodes [164,166] , pressure sensors [272,337,338] , motion sensors [166] , and temperature sensors [166] . Because of low [165], copyright 2014 dissolution rates, Si is typically used as the electrode materials for implantable transient sensors.…”

Bioresorbable electronics that can dissolve away in aqueous environments and generate biologically safe products offers revolutionary solutions for replacing current built-to-last electronics predominantly used in implanted devices and electronic gadgets. Its contribution involves reducing the risk of surgical complications by minimizing the number of surgeries required and preventing the production of electronic waste by allowing rapid device recycling. This text presents bioresorbable materials (e.g. metals, polymers, inorganic compounds, and semiconductors) that have been used to construct electronic devices and analyzes their unique dissolution behaviors and biological effects. These materials are combined to yield representative devices including passive and active components and functional systems.
