Abstract
Self-healing memristor devices were fabricated in this study using a cost-effective and structurally uncomplicated hydrogel consisting of polyvinylalcohol, sodium alginate, and sodium tetraborate. The device is environmentally friendly, biocompatible, possesses a good switching ratio (~ 50), stable memristor under long time run (> 2000 s), and is able to mimic the learning and forgetting functions. In addition, the device could complete the self-healing process at room temperature to rapidly recover its structure and the memristor function. Therefore, it shows great potential for bioelectronics, data storage, and data encryption.
