a Photograph of a 5 × 5 pixels touch panel with cross-stitched TE fibers. b Signals of the TE fibers when the node is contacted with different object temperatures. Inset: simulated temperature distribution of the (3,3) node in contact with 50 °C object. c The resulting signal of the panel when touched by a finger at (3,3) node. d Circuit diagram of the touch panel. e Photo of a “NUS” writing on the touch panel. f The absorption spectrum of the SWCNT/PVA fiber. Inset: temperature evolution of the fiber when irradiated by a beam of light with 1000 W/m2. g The signals of the TE fibers when the node is irradiated by light with different intensities. h Light communication demonstration that sense the incident light direction.
