was drop-casted into a soft PDMS reservoir and heated until gelation to form electrodes. The TR-CP device was adhered to skin using a transparent dressing, along with a heating patch to ensure a stable temperature throughout the experiment. The device was used to record fist closing and opening movements (Fig. , Supplementary Video 4). We observed that in comparison to commercial electrodes, the TR-CP device displayed a higher signal amplitude (250×) with minimal parasitic noise (Fig. ). We attributed this performance enhancement to the mixed ionicelectronic conductivity of the TR-CP and shape-conforming behavior due to its soft and adaptable mechanics. The low modulus of this soft electronic interface prevented any discomfort on skin and provided good conformal contact throughout the measurement. Post-recording, the electrodes were cooled down and TR-CP liquid was extracted, thus demonstrating the reusability of the TR-CPs (Fig. ) and their potential for use as shape-conforming bioelectronic interfaces which could be harnessed for measurements on non-uniform surfaces such as hairy skin.
