Here, we present a self-powered wireless metal detector enabled by the triboelectric discharge effect, inductive coupling, and a signal modulation strategy. The device can convert mechanical triggers into wireless electromagnetic waves that contain information on nearby metals. Based on this strategy, we fabricated two prototypes with different sizes and different trigger modes, thus showing the capabilities and scalability for metal detection under different scenarios. In addition, because of the differences in the waveforms of the electromagnetic (EM) waves triggered by different types of metal, the device can also recognize the type of metal with the assistance of a trained machine learning model.","PeriodicalId":101324,"journal":{"name":"Device","volume":"38 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the existing strategies encounter tough obstacles on their way to commercialization due to their low efficiencies and high costs. Herein, we propose a passive thermal management strategy that relies on moisture desorption from hygroscopic salt solutions through a protective membrane that only allows water vapor to pass through; importantly, it can spontaneously recover cooling capacity during off hours. We selected lithium bromide as a cost-effective sorbent while avoiding crystallization. Outstandingly, the strategy can provide an effective cooling capacity (ΔTmax = 11.5°C) for ∼400 min, while the measured heat flux can reach 75 kW/m2. By employing the strategy in a real computing device, its performance is improved by 32.65% with a record-high cost effectiveness. The strategy can be useful for various applications that need intermittent thermal regulation, with few technological barriers.","PeriodicalId":101324,"journal":{"name":"Device","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136128677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method improves the ease and efficiency of programming muscle force directionality and synchronicity for applications ranging from medicine to robotics.

Implantable microdevices placed directly in the central nervous system (CNS) represent a promising area of investigation in neuro-oncology. In this review, we provide an overview of the control mechanisms, release kinetics, outcomes, strengths, and limitations of implantable microdevices in clinical and laboratory studies. Eight implantable microdevices that delivered various compounds, including chemotherapy, immunotherapy, and nitric oxide, were identified. Device control functions varied from no control after implantation to active coordination of the release of multiple drugs at different rates. We find that, although the devices can reliably deliver therapeutic compounds to the tumor site, their efficacy in terms of prolonging survival and achieving durable remission remains modest. Our findings reveal a critical narrative that emphasizes the unsolved barriers impeding clinical success of implantable microdevices in neuro-oncology.","PeriodicalId":101324,"journal":{"name":"Device","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136010191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photovoltaic neuromodulation using light from the second near-infrared (NIR-II) spectrum, which minimizes scattering and enhances tissue penetration, shows promise as an alternative to existing neuromodulation technologies. NIR-II light has been used in deep-tissue imaging and in deep-brain photothermal neuromodulation via nanotransducers.

We integrated a gantry-type robot carrying a multipurpose nozzle assembly to dispense and mix solutions as well as degas and clean a cell containing multiplexed microelectrochemical arrays. The system operates using Python code and a universal Arduino-based controller. We demonstrate the Electrolab by autonomously analyzing a redox mediator by performing 200 voltammograms and data analysis steps across a range of conditions. In addition, the Electrolab is used to titrate a redox-active polymer solution to identify conditions for optimizing electrochemical performance. Overall, the Electrolab device enables high-throughput, systematic exploration of redox electrolytes, opening new avenues for closed-loop optimization.","PeriodicalId":101324,"journal":{"name":"Device","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135606888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we present an implantable wireless glucose monitor made with on shape-memory electronic device (SMED) that can be implanted with minimal invasiveness. The device is fabricated by printing an inductive-capacitive (LC) circuit and a poly(3-aminophenylboronic acid) (PAPBA)/glucose oxidase (GOx)/graphene oxide (GO) sensing layer on a shape-memory poly(D,L-lactide-co-caprolactone)-based (PCLAU) layer. To demonstrate, the glucose monitor was rolled up, injected into mice using a syringe, and later recovered to its original planar shape under mild thermal stimulations. The biocompatible SMED has high sensitivity, specificity, and reversible sensing characteristics with a broad linear detection range, providing an accurate and reliable platform for in vivo continuous glucose monitoring. This strategy reduces the wound area by ∼73% and the required healing time by ∼45%, thus effectively addressing the general problem faced by implantable devices.","PeriodicalId":101324,"journal":{"name":"Device","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136059418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
