Article Abstract
Stretchable soft antennas represent a transformative class of devices that seamlessly integrate wireless communication into deformable and dynamic platforms. Enabled by advances in functional materials and structural engineering, these antennas can withstand large mechanical deformations while maintaining stable electromagnetic performance - unlocking new possibilities in wearable electronics, soft robotics, and implantable biomedical systems. This review systematically surveys recent progress in conductive material choices - from traditional metals and liquid metal to nanocomposites and hybrid architectures - and examines how structural strategies such as serpentine layouts, kirigami patterns, and out-of-plane designs redistribute strain to preserve antenna performance under repeated deformation. We also discuss emerging fabrication techniques and applications in wireless health monitoring, soft robotic systems, and energy harvesting. Finally, we highlight key challenges, including improving environmental stability, achieving seamless multi-module integration, and unraveling the coupling mechanisms between mechanical deformation and electromagnetic behavior. This review offers a materials and structure driven framework for the rational design of stretchable soft antennas with robust wireless functionality.

Nano-electronics based neural implants represent a rapidly advancing interdisciplinary domain at the intersection of bioelectronics, nanotechnology, and neuro-engineering. These implantable systems are engineered to restore, modulate, or augment neural functions by establishing high-fidelity, long-term interfaces with neural tissues. The design of such implants necessitates careful consideration of both materials and structural configurations to ensure biocompatibility, mechanical compliance, electrical functionality, and chronic stability.

Silk fibroin (SF)-based flexible electronic/photonic materials have gained great attention in wearable devices and soft sensors. However, it remains challenging to understand the molecular interaction mechanisms and subsequently fabricate SF-based flexible materials that exhibit fluorescence, humidity sensitivity, and conductivity properties. In this study, by incorporating lanthanide europium ion (Eu), the design and fabrication of a flexible, fluorescent, and conductive SF membrane was proposed.

Vagus nerve stimulation (VNS) is a promising therapy for neurological and inflammatory disorders across multiple organ systems. However, conventional rigid interfaces fail to accommodate dynamic mechanical environments, leading to mechanical mismatches, tissue irritation, and unstable long-term interfaces. Although soft neural interfaces address these limitations, maintaining mechanical durability and stable electrical performance remains challenging.

Low-fat mozzarella cheese (LFMC) has started to increase in popularity among health-conscious consumers. Unfortunately, the inadequate meltability and rubbery texture of LFMC make it undesirable for many consumers.

Hydrogel actuators show tremendous promise for applications in soft robots and artificial muscles. Nevertheless, developing a stretchable hydrogel actuator combining remote actuation and real-time signal feedback remains a challenge. Herein, a light-responsive hydrogel actuator with self-sensing function is fabricated by employing a localized immersion strategy to incorporate polyacrylamide (PAM) hydrogel network into semi-interpenetrating carbon nanotube/2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofiber/poly(N-isopropylacrylamide) (CNT/TOCN/PNIPAM) hydrogel.
