Abstract: We present a fully energy-autonomous temperature-to-time converter (TTC) for biomedical applications. This is the first work in literature to power the entire converter purely by a triboelectric energy harvester (TEG). The dynamic leakage suppression full-bridge rectifier (DLS-FBR) reduces reverse leakage current to 1/100, which enables the TEG operated by human motion at $\mu \text{m}$ 1P6M CMOS consumes 0.14 pJ/conversion while powered up purely by a TEG, achieving energy-autonomous operation.
