Electronic devices are typically made with non-degradable and sometimes toxic inorganic semiconductors and also require high-vacuum and high-temperature manufacturing processes. With rapid technological advancement and electronic product upgrading, the colossal demand for electronics has led to a huge amount of electronic wastes and rapid consumption of scarce elements (e.g. gallium, indium etc.). Future demands for internet of things (IoT) require an even larger number of low-cost electronics and will impose more influences to the environment. Electronic devices with low cost, good biocompatibility, and less environmental pressure are highly desired. Here we report a degradable and biocompatible conjugated polymer for thin-film transistors. We fabricated fully degradable and biocompatible field-effect transistors (FETs) and pseudo-CMOS type flexible devices on an ultrathin degradable substrate. The flexible device is degradable and biocompatible with ultralight weight (ca. 2 g/m<sup>2</sup>) and low operation voltage (4 V), thus demonstrating its potential applications in low-cost, green, and imperceptible electronics.
