“Luminescent Tentacles” by Nakayama

The Luminescent Tentacles is an interactive art that is inspired by waving tentacles of sea anemones under the sea. The 256 shape-memory alloy actuators react to hand movement and the top of the actuator softly glows like a bioluminescent organism. Each actuator is actuated by three shape-memory alloy wires. The actuator can bend in six directions by the combination of three currents. The control application interacts with fluid dynamics to realize a kinetic representation like a water ripple. The sound reaction to hand movement creates music. The Luminescent Tentacles provides a comfortable interaction like interacting with sea anemones.
