Unlike mechanically passive, rigid systems that often require open surgery, these systems enable compact insertion followed by programmable in situ deployment through diverse actuation mechanisms, including fluidic unfolding and eversion, magnetically guided deformation, thermally triggered shape-memory polymers, and electrically driven elastomeric actuators. In this review, we systematically categorize recent advances in soft robotic actuation strategies for implantable bioelectronics and analyze how these mechanisms facilitate minimally invasive delivery, adaptive conformal interfacing, and multifunctional operation across various organ systems. We further discuss complementary materials and structural innovations—such as bioresorbable platforms, tissue-adhesive interfaces, and mechanically optimized architectures—that enhance chronic stability and biocompatibility. Beyond summarizing recent demonstrations, this manuscript identifies two critical gaps hindering clinical translation: the lack of systematic evaluation of actuator-induced mechanical effects on biological tissues and the limited integration of intrinsic self- and environmental sensing for closed-loop operation. By outlining these challenges and emerging research directions, this review aims to provide a conceptual framework for the rational design and future development of next-generation minimally invasive soft robotic implants. 2026-02-28T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60091 Title: Soft Robotic Implants: A new perspective for minimally invasive bioelectronic interfaces enabled by soft robot technologies Author(s): Song, Sukho Abstract: This paper introduces “soft robotic implants,” a novel approach combining soft robotics and bioelectronics to enable minimally invasive implantation through small incisions. Utilizing various actuation mechanisms like everting, unfurling, and bending, the technology integrates functional components such as electrodes, light sources, and strain sensors for adaptable and efficient deployment on diverse target organs. A prototype soft robotic electrode array for electrocorticography (ECoG) demonstrated successful deployment of electrode arrays via eversion and recording of somatosensory evoked potentials in a minipig, showcasing minimal tissue damage and enhanced procedural safety. Future directions focus on miniaturization, biocompatible materials, and expanded applications, with the potential to revolutionize healthcare by improving efficiency, reducing costs, and creating new markets for soft bioelectronics. 2025-02-05T15:00:00Z
