Abstract
This study introduces implantable printed electronics by incorporating highly conducting inkjet-printed PEDOT:PSS traces into PVA cryogel matrices, forming robust, biocompatible electronic cryogels for long-term use inside plant tissue. These cryogels, fabricated using a peeling method and freeze-thaw cycling, exhibit high conductivity, stretchability (up to 330% strain), self-healing properties, and design flexibility. Successful implantation in tomato plant stems enabled ionic activity monitoring for over two months with minimal scar tissue formation.
