Movie S1
A transparent ionic touch panel was operated after being glued onto an LCD monitor. A polymethylmethacrylate (PMMA) film was placed between the monitor and the ionic touch panel for insulation. A dashed man was displayed as an input figure on monitor #1. When the dashed man was drawn by a finger on the ionic touch panel, the output figure simultaneously appeared on monitor #2.
Movie S2
An ionic touch panel in a circular shape (diameter = 4 cm) was stretched equi-biaxially up to 1000 % of the areal strain. The diameter of the panel was 12.5 cm after stretching. The panel could be operated in a highly stretched state.
Movie S3
An epidermal touch panel was used to write a word. The panel had a sufficient resolution to recognize the hand writing, and it could detect an arbitrary motion of touching.
Movie S4
A tune (Twinkle Twinkle Little Star) was played using the epidermal touch panel. A computer program “Perfect Piano� was used for the demonstration. The positions of keys in the panel were previously investigated before playing. The panel reliably sensed the position of the touching.
Movie S5
Chess was played using the epidermal touch panel. A “tapping� gesture was used to select a pawn, and a “dragging� gesture moved a piece.
Movie S6
Angry Birds was played by using the epidermal touch panel. The epidermal touch panel could successfully perceive various motions, such as tapping, holding, dragging, and swiping.
