Current overdose reversal systems face key limitations, including low user adherence, false positive detection, and slow antidote delivery. Here, we describe a subcutaneously implanted robotic first responder to overcome these challenges. This implantable system for opioid safety continuously monitors vital signs, detecting opioid overdose through an algorithm analyzing the interplay of cardiorespiratory responses. To address battery concerns with continuous monitoring and multi-sensing modality, an adaptive algorithm dynamically adjusts sensor resolution, reducing the need for frequent charging. Furthermore, the implant includes an ultra-rapid naloxone delivery pump, delivering the 10-mg antidote within 10 s. In animal trials, the robotic first responder successfully revived 96% of overdosed pigs (<i>n</i> = 25) within 3.2 min, showcasing its potential to dramatically improve survival rates and combat the opioid epidemic.</p>","PeriodicalId":101324,"journal":{"name":"Device","volume":"2 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11735030/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically within a clinical setting, repetitive strength-based and task-specific exercises are prescribed. However, these therapies are generally costly and non-portable, limiting patient accessibility and rendering patient compliance impractical. There is thus a clinical need for a system that is low-cost, portable, and accessible to improve patient compliance and outcomes. This work presents a proof-of-concept magnetically-controlled glove to provide targeted resistance-based rehabilitation for patients with hand motor impairments. The glove is inexpensive, customizable, and portable, allowing for use within a clinic and at home. Customizable resistance is achieved by electropermanent magnets (EPMs), which locally control magnetic attraction of the digits and produce rapid stiffness changes from magnetically induced jamming. Various rehabilitative exercises using the glove are demonstrated and the magnetic fields can be customized to provide necessary resistance.</p>","PeriodicalId":101324,"journal":{"name":"Device","volume":"2 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11864777/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
