  • Thin film lithium batteries
    Solid State Ionics, 2002
    Co-Authors: J Souquet
    Abstract:

    International audienceNew electrolyte materials, polymers or inorganic glasses, allow the design of flat lithium primary or secondary batteries for miniaturised devices from smart cards to CMOS back up. The so-called “hybrid plastic electrolytes” allow the design of thick film cells (1–3 mm) with a surface capacity of some mA h cm−2. For Li-ion secondary batteries, the number of cycles does not currently exceed 500.All solid state thin film batteries are manufactured using sputtering and vacuum evaporation techniques. Their thickness and surface capacity are about one order of magnitude lower than for the polymer electrolyte batteries. In spite of metallic Li anodes, they offer a better cyclability and the solid state of all components guaranties no Liquid Leakage

  • twinleak rfid based Liquid Leakage detection in industrial environments
    International Conference on Computer Communications, 2019
    Co-Authors: Junchen Guo, Ting Wang, Meng Jin, Chengkun Jiang, Yunhao Liu
    Abstract:

    Liquid Leakage detection is a crucial issue in modern industry, which concerns industrial safety. Traditional solutions, which generally rely on specialized sensors, suffer from intrusive deployment, high cost, and high power consumption. Such problems prohibit applying those solutions for large-scale and continuously industrial monitoring. In this work, we present a RFID-based solution, TwinLeak, to detect Liquid Leakage using COTS RFID devices. Detecting the Leakage accurately with coarse-grained RSSI and phase readings of tags has been a daunting task, which is especially challenging when low detection delay is required. Our system achieves these goals based on the fact that the inductive coupling between two adjacent tags is highly sensitive to the Liquid leaked between them. Therefore, instead of judging according to the signals of each individual tag, TwinLeak utilizes the relationship between the signals of two tags as an effective feature for Leakage detection. Specifically, Twin-Leak extracts discriminative signal features from short segments of signals and instantly identifies Leakage using a light-weight classifier. A model-guided method for Leakage progress tracking is further devised to simultaneously estimate the Leakage volume and rate. We implement TwinLeak, evaluate its performance across various scenarios, and deploy it in a real-world industrial IoT system. In average, TwinLeak achieves a TPR higher than 97.2%, a FPR lower than 0.5%, and a relative property estimation error around 10%, while triggering early alarms after only about $4.6mL$ Liquid leaks.
