Design and fabrication of the degradable OECTs. (a) Layout of the two OECT designs (PEDOT:PSS-gated and carbon-gated). (b) Picture of a PEDOT:PSS-gated device. (c) Recording setups used in the experiments: PMMA reservoir (top) and microchannel (bottom). (d) Fabrication process for the additive manufacturing of degradable OECTs: (i) PLA substrate casting and surface modification, (ii) carbon paste stencil printing and curing and (iii) inkjet printing of PEDOT:PSS channel and curing. (e) Degradation of a transient device in soil at different timepoints.
