“…The peeling test further demonstrated that the adhesion at the interface was enhanced because of the presence of hydrogen bonds between the CO groups of PVP and OH groups of gelatin (Figure S3). This enhanced adhesion between conductors and substrates was previously reported to enhance the mechanical properties of the stretchable conductors . As a result, we can stretch our stretchable transient conductor to 100% without any failure and with good recovery (Figure e).…”

Transient conductors are one of the most important components in transient electronics, which attract great attention because of their environment-friendly and biocompatible characters. To meet the requirement for wearable electronics, good stretchability and mechanical durability are needed for the transient conductors. However, it remains challenging to achieve stretchability and transient behavior simultaneously because of a lack of the proper elastomer. Herein, we demonstrate the first highly stretchable and transient conductor from a composite material of Ag flakes and gelatin hydrogel. It shows a maximum stretchability of more than 100% with minimal resistance increase and a good cyclic durability of 1000 cycles of deformation at 20%. The above mentioned good mechanical properties come from the rational design of the conductor with a seamless interface between the hydrogel and Ag flakes. When the conductor is immersed in water at 60 °C, it can be quickly dissolved within 90 s, and the transient behavior can be controlled by tuning the content of the hydrogel in the conductors and dissolving temperature. These properties make the conductor a good wiring candidate for stretchable and transient electronics.

A wide variety of low‐dimensional nanomaterials with excellent properties can meet almost all the requirements of functional materials for information sensing, processing, and feedback devices. Low‐dimensional nanomaterials are becoming the star of hope on the road to pursuing human–machine–thing natural interactions, benefiting from the breakthroughs in precise preparation, performance regulation, structural design, and device construction in recent years. This review summarizes several types of low‐dimensional nanomaterials commonly used in human–machine–thing natural interactions and outlines the differences in properties and application areas of different materials. According to the sequence of information flow in the human–machine–thing interaction process, the representative research progress of low‐dimensional nanomaterials‐based information sensing, processing, and feedback devices is reviewed and the key roles played by low‐dimensional nanomaterials are discussed. Finally, the development trends and existing challenges of low‐dimensional nanomaterials in the field of human–machine–thing natural interaction technology are discussed.

“…[ 5b ] They have a conjugated backbone and become highly conductive when in doped state. [ 6 ] Doping is carried out by oxidizing or reducing the conjugated polymers. As the charge transport is usually dominated by the interchain charge carrier hopping, the conductivity of ICPs greatly depends on the crystallinity as well.…”

Since the discovery of conducting polyacetylene in the 1970s, intrinsically conducting polymers (ICPs) have attracted great attention because of their interesting structure, properties, and applications. Notably different from conventional conductors such as metals and doped semiconductors, ICPs have high mechanical flexibility and are light weight. In addition, their properties can be easily tuned by controlling the doping level, modifying the chemical structure, or forming composites with organic or inorganic materials. Their application in bioelectronics is particularly interesting because they have good biocompatibility and good mechanical matching with biological tissues. In this article, the methods to increase the mechanical stretchability of ICPs are first reviewed because high stretchability is often required for bioelectronic applications while pristine ICPs generally have limited stretchability. The application of ICPs as stretchable electrodes for epidermal biopotential detection and neural interfaces is discussed. Then, the employment of ICPs as the electrodes or sensing material of mechanical sensors is reviewed. They also have important application in controllable drug delivery. Last, their applications in the wearable energy harvesting and storage devices including thermoelectric generators and supercapacitors are also covered.
