Hydrogel-based bioelectronic systems offer significant benefits for point-of-care diagnosis, treatment of cardiac and cerebral disease, surgical procedures, and other medical applications, ushering in a new era of advancements in medical technology. Progress in hydrogel-based bioelectronics has advanced from basic instrument and sensing capabilities to sophisticated multimodal perceptions and feedback systems. Addressing challenges related to immune responses and inflammation regulation after implantation, physiological dynamic mechanism, biological toxicology as well as device size, power consumption, stability, and signal conversion is crucial for the practical implementation of hydrogel-based bioelectronics in medical implants.

Complex internal stresses that appear in flexible thin-film electronic devices under long-term deformation operation are associated with incompatible mechanical properties of the multiple layers, which potentially cause intralayer fracture and separation. These defects may result in device instability, performance loss, and failure. Herein, a thermoplastic functional strategy is proposed for manufacturing high-performance stretchable semiconducting polymers with excellent strain-tolerance capacities for flexible electronic devices.

Hydrogels have received great attention due to their molecular designability and wide application range. However, they are prone to freeze at low temperatures due to the existence of mass water molecules, which can damage their flexibility and transparency, greatly limiting their use in cold environments. Although adding cryoprotectants can reduce the freezing point of hydrogels, it may also deteriorate the mechanical properties and face the risk of cryoprotectant leakage.

The development of healable polymers represents a significant advancement in materials science, addressing the need for sustainable solutions that can reduce waste and prolong the lifespan of various products. For the development of healable polymer fabrics, however, there are still unsolved issues because of limited healing cycles and poor mechanical properties. In this work, we present intrinsically healable materials for the creation of stretchable, healable fabrics.

Fully π-conjugated polymers consisting of plane and rigid aromatic units present a fantastic optoelectronic property, a promising candidate for printed and flexible optoelectronic devices. However, obtaining high-performance conjugated polymers with an excellent intrinsically flexible and printable capacity is a great challenge due to their inherent coffee-ring effect and brittle properties. Here, we report an asymmetric substitution strategy to improve the printable and stretchable properties of deep-blue light-emitting conjugated polymers with a strong inter-aggregate capillary interaction for flexible printed polymer light-emitting diodes.
