Description

technical field [0001] The invention belongs to the technical field of manufacturing and packaging of electronic pressure sensors, and in particular relates to a flexible electronic pressure sensing device and a preparation method thereof. Background technique [0002] As people pay more and more attention to their own health, they are gradually keen on wearable devices that can collect real-time physiological parameters and analyze exercise status. As one of the core components of wearable devices, the sensor system has limited the further development of wearable devices due to its insufficient flexibility. In the application of real-time health detection, implanted medical devices, smart home and skin electronic devices, there is an urgent need for high-tech performance flexible electronics. Most of the current pressure sensors are still made of inorganic materials such as silicon. Once stretching or bending deformation occurs, the hardware structure of the sensor will b...
