To address this urgent need, we developed a non-invasive and wearable electrochemical glucose sensor patch based on a platinum-copper (Pt-Cu) nanocomposite electrodeposited on carbon cloth thread (CCT) electrode after functionalizing with an electropolymerized polyphenol (Pphe)-glucose oxidase (GOx) film. The immobilization of GOx via the formation of a polyphenol film was done by electropolymerization of phenol in presence of GOx. The detection capability of the developed sensor was evaluated by chronoamperometry analysis and found that the sensor is able to detect glucose with wide linear detection range from 100 to 1500 μM with an ultra-low limit of detection (LOD) of 31.1 μM and 64.4 μM for artificial sweat and urine respectively. In addition, the developed sensor is found to be reproducible, repeatable and highly selective in presence of common interfering molecules present in the human samples. Furthermore, the developed sensor was seamlessly integrated into a wearable prototype device on a commercial bandage with custom made potentiostat circuit called Nanopot. The developed wearable prototype sensor system also exhibits a wide linear detection range from 300 to 1500 μM and a promising LOD of 25.8 μM.

Moreover, the employees working near any strong magnetic environment would benefit by avoiding high exposure. This research delves into a comprehensive process for the implementation and characterization of such a wearable based on the magnetoresistance effect, which is a function of the magnetic field. The program executes on the Arduino IDE platform. Samples are taken for varying magnetic flux density along each axis, for changes in distance of 2.5 mm. The calculations take place accordingly and provide outputs in microtesla units. Subsequently, the device is analyzed by plotting the responses, and it also helps to understand the working procedure. For a certain axis, the magnetic field is generally stronger than others. The goal is to determine the highest absolute value at any instance, including the Earth's geomagnetic field of 22–67 μT. Regulatory standards are followed to divide the magnetic flux density into four states: power saver (below 150 μT), safe (150–500 μT), unsafe (500–750 μT), and danger (over 750 μT). These values consist of ±20 μT error, which is quite insignificant. Depending on the state, the novel device generates different warning signals to mitigate risk from magnetic fields. From the error bar plot, it is realized that the percentage of error decreases while calculating higher magnetic flux. The errors could be reduced remarkably by ensuring better calibration and compensation techniques in the future.</div></div>","PeriodicalId":260,"journal":{"name":"Biosensors and Bioelectronics: X","volume":"26 ","pages":"Article 100654"},"PeriodicalIF":10.61,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144522769","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}

Through a combination of numerical simulations and theoretical analyses, it is demonstrated that the coupled HH–resonator system achieves stable limit cycles and significant mechanical displacements via parametric amplification. This amplification arises from the nonlinear capacitive coupling, which leads to Mathieu-like equations governing the system's dynamics, thereby enabling large oscillations from relatively small voltage inputs. Such parametric resonance is critical for the device's ability to sustain oscillatory motion, making it highly suitable for integration into compact and implantable MEMS applications. Potential applications include implantable sensors and actuators for real-time physiological monitoring, and advanced micro-scale systems that benefit from biologically sourced energy.
