Abstract Driven by the growing burden of chronic diseases and limited public healthcare resources, portable health monitoring platforms are widely developed to enable continuous timely dissemination provide users with management disease prevention. However, it is still a challenge for precision fully bio‐integrated electronic devices achieve stable physiological signal recording over long periods time. Recently, semi‐implantable bioelectronics (SI‐bioelectronics) have excelled in real‐time, long‐term, high‐sensitivity pathological signals minimal invasiveness, enabled precise microneedle sensing probes. In this review, comprehensive overview recent advancements SI‐bioelectronics provided, focus on their structures, design considerations, performances biochemical indicators, bioelectrical signals, biomechanical signals. Opportunities research such as smart medicine Internet Things also discussed, which will drive toward intelligence efficiency.

With the goal of impacting patient quality life and outcomes, sensor science offers significant potential to revolutionize healthcare by providing advances in detection molecular biomarkers for personalized clinical technologies. The community has achieved technical advancements that can impact diagnostics, health monitoring, disease treatment; however, many innovations remain confined laboratory, failing bridge translational gap between research real-world applications. This perspective presents a new direction community, where development centers on needs experiences primary beneficiaries: patients. We provide guidelines resources researchers engage with patients early continuously throughout process inform specifications better align technologies needs, improving their adoption impact. also present examples implementing patient-centered approach planning engagement research. In design impactful sensors patients, must expand focus beyond embrace approach, which will likely lead opportunities collaboration evolution community.
