Schematic diagram of the fabrication process for the nanowire-microfluidic hybrid (NMH) strain sensor. a Attach PI tape to a glass substrate. b Deposit nanowires or nanotubes onto the PI tape to form conductive thin films. Scanning electron microscopy (SEM) images of the synthesized copper, silver nanowires, or carbon nanotubes are shown above (the scale bars represent 400 nm). c Pour and impregnate the conductive thin film with uncured Ecoflex. d Peel off the Ecoflex film after curing. e Attach silver wires and encapsulate. f Inject the PEDOT:PSS solution and seal the channel with Ecoflex. Photos of the obtained NMH sensors under different scales of stretching are also shown
