Important results from the project
This project aims at developing a new flexible, low cost, robust, self-powered vibration sensor for smart technological improvements. A flexible self-powered sensor has been developed by using a novel flexible electrode based on an iongel material.
Expected long term effects
In the proposed project, an ionogel was prepared via dissolving acrylamide or other monomer and photo-initiator with some ratio into ionic liquid. Based on the developed iongel, a flexible TENG vibration sensor was developed, which shows its possibility to replace and/or complement current commercial vibration sensors in wide applications. The proposed project also gives companies higher competitiveness at both the national and regional level in areas such as digital development and sustainable production towards Industry 4.0.
Approach and implementation
2020.1-2020.06: Preparation and performance test of ionogel; The ionogel was prepared by dissolving acrylamide or other monomer and photo-initiator with some ratio into ionic liquid. The thermal stability, electric conductivity, mechanical properties of ionogel will be done in this project. 2020.07-2020.10: TENG sensor assemble and output test The ionogel based TENG sensor will assemble. The open-circuit voltage will be measured by using a Keithley 6514 system electrometer. Every planned activity has been well carried out.
