Accordingly, the artificial replacement or support of impaired sensory function has become one of the main objectives of neural engineering and neuroprosthetics. This review systematically organizes auditory, visual, and somatosensory restoration technologies by target organ-from peripheral sensory organs to the central nervous system-and provides a comprehensive overview of the achievements and limitations of each approach. Auditory restoration includes cochlear, brainstem, and auditory cortex approaches; visual restoration includes retinal, optic nerve, and visual cortex approaches; and somatosensory restoration includes somatosensory cortex and peripheral nerve approaches. Although neuroprosthetics-based sensory restoration technologies have achieved considerable progress, the sensations currently restored remain far from natural perception. This review discusses future directions to address these limitations, focusing on higher-density electrodes, device and system optimization, decoding-based biomimetic stimulation, and personalized stimulation strategies. Ultimately, these advances may enable more natural sensation and improve the quality of life of patients with sensory impairments. 2026-08-31T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60962 Title: Thermoresponsive Soft and Self-Anchoring Cuff Electrode for Chronic Peripheral Interfaces Author(s): Lee, Seungjun; Park, Byungwook; Eun, Jonghee; Kim, Sohee; Chou, Namsun Abstract: Cuff type neural interfaces are widely used for peripheral nerve stimulation and monitoring. The traditional cuff electrodes typically require sutures or rigid fixation; this can lead to nerve damage and unstable electrode contact, ultimately compromising long-term performance. To address these issues, we developed a thermoresponsive soft and self-anchoring (TSSA) cuff electrode that automatically wraps around nerves in response to body temperature. This functionality is made possible by a shape memory polymer (SMP) substrate designed to soften and deform near physiological temperatures, enabling the electrode to self-close and securely hold without the need for an external force. Additionally, the SMP provides gentle yet stable contact with the nerve, thereby enhancing biocompatibility. In vivo experiments using rat sciatic nerves demonstrated reliable recordings of mechanically evoked nerve responses for 16 weeks, with signal-to-noise ratios reaching approximately 10 and stable impedance profiles. Histological and immunohistochemical analyses showed no significant tissue damage or inflammatory responses caused by the implanted device. By removing the need for sutures and providing a soft, stable contact with the nerve, the cuff electrode represents a safe and durable platform for chronic neural interfacing. The proposed technology holds strong potential for use in prosthetic limbs and bioelectronic medicine. 2026-08-31T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60429 Title: 하이브리드형 신경 전극 Author(s): 장재원; 김소희 Abstract: 하이브리드형 신경 전극이 개시된다. 본 하이브리드형 신경 전극은, 평면형 전극이 배치되는 하면 및 상하로 관통 형성된 복수의 홀을 포함하는 제1 층 및 제1 층의 상면을 바라보고 신경 신호의 측정을 위한 측정 장치가 배치되는 하면을 포함하는 제2 층을 포함한다. https://scholar.dgist.ac.kr/handle/20.500.11750/60330 Title: 풍선 타입 망막 자극장치 및 이의 제조방법 Author(s): 문현민; 김소희; 추남선 Abstract: A balloon type retinal stimulation device includes: a substrate unit having an insertion portion provided to be inserted into an eyeball; and a stimulation unit that is provided at one or both of one and the other surfaces of the substrate unit. The insertion portion is provided to be expandable and contractible as a fluid is injected into and discharged from an inside of the injection portion. When the insertion portion expands, one surface of the insertion portion is deformed to match a shape of the retina such that the stimulation unit is brought into close contact with the retina on which an image is formed, and the other surface of the insertion portion comes into close contact with an inner surface of the eyeball that is not a region of retina on which an image is formed, to support the insertion portion that is in contact with the region of retina on which an image is formed.
