Abstract: Conductive and transparent dipeptide hydrogels are desirable building blocks to prepare soft electronic devices and wearable biosensors due to their excellent biocompatibility, multi-functionality, and physiochemical properties similar to those of body tissues. However, the preparation of such hydrogels featuring high conductivity and transparency is a huge challenge because of the hydrophobic feature of conductive additives making the doping process difficult. To overcome this issue, hydrophilic conductive polydopamine (PDA)-doped polypyrrole (PPy) nanoparticles are introduced into the dipeptide hydrogel networks to form conductive nanofibrils in situ to achieve a good level of hydrophilic templating of the hydrogel networks. This technique creates a complete conductive network and allows visible light to pass through. The strategy proposed herein not only endows the dipeptide hydrogel with good conductivity and high transparency, but also provides a great potential application of conductive dipeptide hydrogels for body-adhered signal detection, as evidenced by the experimental data.
