Earlier sources: Sensors
This hardware thread follows sensors through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗13 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Bio‐Inspired Gradient Heterogeneous Architectures for Ultrasensitive and Robust Strain Sensors via Programmable Crack Engineering ↗
ABSTRACT The development of flexible strain sensors is crucial for next‐generation wearable medical devices and human‐machine interfaces (HMIs). While conductive networks based on random microcracks have been widely employed to enhance sensor responsiveness, they are often limited by trade‐offs between sensitivity and measurement range. Inspired by the stress concentration mechanism in insect campaniform sensilla (CS), this study proposes a biomimetic heterogeneous bilayer strain sensor based on a deterministic macrostructure. The sensor employs a bilayer cladding architecture with a U‐shaped…

Carbon-based materials coupled with metal oxide semiconductors for hydrogen sensors: linking mechanisms and dimensions ↗
Reliable H 2 detection is essential for hydrogen energy systems, industrial processing, battery safety, and clinical monitoring. Chemiresistive sensors based on metal oxide semiconductor (MOS) are widely used because of their low fabrication cost and facile integration. However, they still suffer from high operating temperatures, limited selectivity, poor humidity tolerance, and insufficient long-term stability. Incorporating carbonaceous materials with large specific surface areas, high carrier mobility, and tunable surface chemistry provides an effective route to address these limitations. T…

Performance Impact of Failure and Recovery Mechanisms in LoRa Sensors ↗
Abstract LoRa sensor deployments are widely used in monitoring applications, where multiple devices generate packets continuously or periodically. In these scenarios, system performance is affected not only by the number of sensors and the packet generation rate, but also by intermittent failures. When a sensor becomes unavailable, packets may be lost and throughput decreases. The recovery time then defines how long the system remains in this degraded condition. Traditional long-term analyses may hide these short-term effects, especially the sudden increase in packet losses during and shortly…

More Sensors Only One Field: Rethinking Continual Spatio-Temporal Forecasting ↗
Continual spatio-temporal forecasting supports traffic management and environmental monitoring under evolving dynamics and expanding sensor networks. However, conventional graph-based continual learning methods tie forecasting representations to the current sensor layout, so sensor expansion can alter the representation of learned spatial relationships. Our key insight is that sensor expansion changes the evidence available about a process without necessarily changing the dynamics to be learned. We propose STFO (Spatio-Temporal Field Operator), which parameterizes forecasting knowledge as a sh…

Temperature Capacitive Sensors Based on Liquid Crystalline Gels ↗
Capacitive temperature sensors are attractive for soft and wearable electronics due to their low power consumption and simple architecture, yet their sensitivity is typically limited by the weak thermal response of conventional solid dielectrics. Liquid crystals, exhibiting strong temperature-dependent properties, represent a promising strategy to overcome this limitation, but their intrinsic fluidity compromises mechanical robustness and long-term stability. Here, we present a capacitive temperature sensor based on a liquid crystal gel (LCG), in which a low-molecular-weight nematic liquid cry…

Integrated Approaches for Development of Gas Sensors: From Nanomaterials and Simulated Environment to Application in Smart Cities ↗
Reliable transition of laboratory-developed gas-sensing nanomaterials into environmental monitoring systems remains limited by the lack of integrated testing platforms capable of reproducing realistic operating conditions while providing automated, high-quality sensor characterization. In this work, we present a comprehensive framework for environmental gas sensor development centered on a custom-designed gas sensor chamber (GSC) and its connection to standalone measuring stations (sMSs) intended for smart city air quality monitoring. The GSC was developed as a dedicated platform for controlle…

Tunneling Magnetoresistance Current Sensors for Power and Energy Systems: A Critical Review of Architectures, Error Mechanisms, and Design Trade-Offs ↗
Current measurement in Power and Energy Systems must accommodate direct-current components, converter harmonics, fast transients, wide dynamic ranges, and strong electromagnetic interference. Tunneling magnetoresistance (TMR) sensors offer high field sensitivity, broad intrinsic bandwidth, compact size, and low power consumption, but these device-level advantages do not directly translate into system-level accuracy or usable bandwidth. The principal contribution of this review is a unified framework organized around sensor architecture that connects magnetic tunnel junction transfer characteri…

How to assess evidence about Sensors
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
