milliMorph -- Fluid-Driven Thin Film Shape-Change Materials for Interaction Design
summary
milliMorph fabricates arrays of millimeter-scale fluidic chambers on 20 μm PET film using a non-contact hot air sealing method that yields sub-millimeter seams and allows metallized PET to be masked, etched and cold-soldered into conductive traces. Samples actuate with liquids, vapors or UV resin and reach responsiveness around 10–30 Hz; a mini robot flaps at 10 Hz but tubing weight prevents lift, sequential folding is controlled by channel-width–dependent flow resistance, and wearable prototypes show quiet, battery-powered heating actuators and touch-sensing buttons.
