As a result, considerable advances have been made, but so far, the focus has been on the integration of various electronic components in the same plane, i.e., in the 2-D configuration, limiting to the low integration density. The 3-D integration could possibly resolve these limitations with lesser layout complexity, lower power consumption, and compact packaging. Toward this direction, we show herein the fabrication of out-of-plane photodetectors (PDs), and vertical interconnects printed on an encapsulated ultrathin chip to develop a 3-D electronic system for ultraviolet (UV) light sensing. The printed PDs show high peak responsivity (R = >106 A/W), and Iphoto/Idark ratio (≈ 103) at the UV light (λ = 365 nm) intensity of 0.5 µW/cm2 and 2 V bias. The photoinduced transfer curves of MOSFETs integrated with the printed PD were obtained at Vds = 0.5, 1, and 2 V under dark and different incident power intensities ranging from 0.5 to 2.5 µW/cm2 with a step of 0.5 µW/cm2. The controlled sensing behavior (i.e., stable low-off currents), evident from the data obtained using the integrated pixel, confirms the potential of presented approach for the development of active-matrix 3-D heterogeneously integrated sensory systems.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 9","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880406","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}

Without having access to manufacturer data, insights into the functional end electrical behavior of the subsystems and their interdependencies inside a vehicle remain unclear. This makes it difficult for research to develop sophisticated optimization solutions for energy consumption and computing power to accelerate the environmental impact reduction of the automotive sector and to fulfill governmental regulations. Existing measurement systems are either expensive or lack measurement granularity, which restricts accessibility to data and results in assumption-based contributions. This work presents a novel low-cost modular in-vehicle sensor system designed to monitor the energy consumption of automotive auxiliary systems. The novelty of this approach lies in breaking down the power consumption to the level of components [electronic control units (ECUs), sensors, and actuators], while supporting correlation with vehicle driving parameters. This approach allows users a wide range of applications for analyzing the computing power of individual ECUs, as well as the traceability of control logics by recording the activation/deactivation of actuators and sensors. The recording allows a digital image of the functions to be created and optimized in a simulation and compared with the real electrical/electronic architecture. This easy-to-integrate system, powered via USB and using adapter connectors for noninvasive setup, offers six channels to measure up to 18 V and 10 A at 200 Hz (12-bit resolution). Validated in a test vehicle on park distance control and surround view systems, it identified how vehicle speed affects sensor activation and ECU power, pinpointing opportunities for idle modes and energy savings.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 9","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144914121","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}

To periodically measure their body mass without excessive disturbance, weight scales have been installed inside nests that have been constructed previously. Conventional weight scales had difficulty with low output drift and maintaining low power consumption. A force plate utilizing the sampling Moiré (SM) method, achieving high resolution and drift robustness in human use, was proposed. An applied force was calculated from a displacement detected by analyzing the stripe pattern captured by a camera. However, if there is a change of more than half the pattern pitch between frames, it cannot be measured correctly. Then, we propose an SM method-based weight scale that can be installed in nests and is suitable for time-lapse measurements, reducing power consumption. The proposed weight scale comprises a top plate supported with springs, an optical prism, and a microcontroller-based camera board. A dual-pitch stripe pattern, incorporating both short- and wide-pitch components, is attached to the backside of the top plate. Plate displacement is measured by analyzing images of the stripe pattern captured through the prism. Correction of the short-pitch results using the long-pitch results resolves phase wrapping and enables both high resolution and a wide measurement range. Calibration experiments of the developed weight scale demonstrated that the dual-pitch approach measured weights up to 2 kg while maintaining a high resolution of 45 mN, which corresponds to 4.6 g. The proposed weight scale is suitable for time-lapse monitoring of body mass in seabird chicks.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 9","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144868350","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}

While most LIG-based sensors have been developed on polyimide substrates, their performance on textile platforms remains underexplored. This study investigates the material properties and performance of a flexible electrochemical biosensor fabricated on a Kevlar textile for noninvasive glucose detection. The biosensor incorporates LIG electrodes functionalized with glucose oxidase (GOx) immobilized in a polyvinyl alcohol (PVA) matrix, along with Prussian Blue (PB) as an electron mediator to enhance electron transfer efficiency. A silver/silver chloride (Ag/AgCl) reference electrode was integrated to ensure stable potential measurements. The electrochemical performance was evaluated using cyclic voltammetry (CV) and chronoamperometry (CA), confirming the sensor's sensitivity and stability across physiological glucose concentrations. The biosensor demonstrated a linear glucose detection range from 0.01 to 2 mM, a sensitivity of 1.85 μA·mM−1, and a calculated limit of detection of 0.0573 mM.

The 50 µm diameter Au, Pt, and 30 µm Ag wires were bonded to commercial printed circuit boards (PCBs) to produce freestanding microneedles (MNs) that served as working (WE), counter (CE), and reference (RE) electrodes. Ag MNs were galvanostatically chlorinated to form Ag/AgCl reference electrodes with low drift, −3 ± 0.3 mV over 24 h in phosphate-buffered saline. Au MNs were coated with PEDOT:PSS/glucose oxidase for amperometric glucose sensing from 5–25 mM (sensitivity = 0.37 µA mM-1, +0.50 V working voltage), covering the physiologic range for diabetes management. Platform versatility was demonstrated by nanomolar-range detection after the addition of an aptamer self-assembled monolayer on wire bonded Au MNs. This fully automated, additive wire bonding process provides submillimetre electrode spacing, < US$2 materials cost per trielectrode array, and seamless integration with external sensing hardware for wearable applications owing to the PCB-substrate based approach. We demonstrate a scalable pathway toward multiplexed MN patches for continuous interstitial fluid monitoring and other microneedle-based minimally invasive biosensing applications.","PeriodicalId":13014,"journal":{"name":"IEEE Sensors Letters","volume":"9 9","pages":"1-4"},"PeriodicalIF":2.2,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11119430","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867649","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}
