Summary: Recent advances in soft materials and nano-microfabrication have made it possible to develop flexible wearable electronics. Printing technologies have shown efficiency and compatibility with polymeric materials for manufacturing wearable electronics. In this study, fully screen-printable, skin-conformal electrodes were presented for low-cost and scalable manufacturing of wearable electronics. The screen printing process enables easy, cost-effective, and high-throughput manufacturing, while the ink used for the conductive layer printing allows for natural deformation under stretching and bending conditions. Real-time wireless electrocardiogram monitoring was successfully demonstrated using the printed electrodes, with an algorithm developed for accurate heart rate and respiratory rate calculations, as well as arrhythmia detection.

Summary: This paper investigates the mechanical behavior of nonbuckling interconnects bonded to a prestrained substrate, finding that larger prestrain, longer straight segments, and smaller arc radii reduce strain in the interconnects. However, releasing the prestrain may lead to larger strains in the interconnects, suggesting the need for optimizing prestrain to achieve favorable stretchability.

Summary: This study proposes a third strategy, an overstretch strategy, which achieves a doubled elastic stretchability of fabricated stretchable electronics by stretching them beyond the designed elastic range after transfer printing and bonding to a soft substrate. This strategy can be easily executed and combined with the other two strategies to enhance elastic stretchability, which has profound implications for the design, fabrication, and applications of inorganic stretchable electronics.

Summary: The demand for stretchable batteries is increasing with the emergence of wearable and epidermal electronics. However, the development of stretchable batteries is a major challenge due to the brittle nature of battery components. This study presents a simple and effective strategy to fabricate stretchable electrodes and separator for Li-ion batteries using 3D printing technology. The resulting components exhibit 50% reversible stretchability and excellent mechanical and electrical performance.

Summary: This study proposes a rationally designed stretchable conductive composite with boron nitride (BN) as a non-conductive auxiliary filler, which significantly increases the electrical conductivity of the composites at low percolation threshold concentration. The introduction of 3μm h-BNs lowers the percolation threshold concentration from 63.3 wt% (14.8 vol%) to 52.0 wt% (9.53 vol%), due to the effective interaction between auxiliary BN and Ag particles. The exfoliated 3μm BNs result in similar electrical conductivity with lower BN concentration, leading to improved electrical stability and excellent adhesion when bent or stretched.

Summary: Kirigami, a traditional paper-cutting art, is used to create mechanically robust circuitry for stretchable devices through structural deformation. This study introduces Liquid Metal based Elastic Kirigami Electrodes (LM-eKE) with eutectic gallium-indium (EGaIn) coating, which can be stretched to 820% strain with only a 33% increase in electrical resistance. The LM-eKE maintains high electrical conductivity even during extreme deformation, allowing for stable electrical operation of wearable health monitoring devices.
