Scientists from the Chinese Academy of Sciences (CAS) in Beijing have successfully developed an invisible electrical circuit inside a polymer (dimethylsiloxane) used for making contact lenses. Professor Song Yanlin and his team from the Institute of Chemistry at CAS were able to create this invisible circuit by injecting droplets of fine silver ink into the polymer.
