\section{Healing chemistry}

\begin{frame}{How the network heals itself}
  \begin{itemize}
    \item Dynamic disulfide bonds exchange at room temperature, so a cut
          interface re-forms crosslinks within hours.
    \item Hydrogen-bonding side chains provide fast initial tack while the
          covalent network recovers.
    \item No added catalyst or heat: healing proceeds under ambient conditions.
  \end{itemize}

  Strain sensors built on the healed substrate survive 10,000 bending
  cycles with under 4\% drift.
