a A circuit diagram and connection mechanisms of a 32 × 24 interleaved assembly array and its wireless interface to a touchscreen device or a laptop. b Pressure response of the pneumatic control unit (top panel) under given control command (bottom panel). The pneumatic control unit has two states, i.e., ‘0’ state (or OFF state) for tubing closed and ‘1’ state (or ON state) for tubing open, which leads to constant or decreased pressures, respectively. The switch of the state of the pneumatic control unit can precisely and quickly vary the pressure response. c Power consumption of the actuation system. During shape-morphing process (e.g., the display of a word “THINK”), the operation of the stepping motor and the steering engines causes transient energy consumption. While during prolonged shape-display process, there is no energy consumption.
