d3o

Developed by d30-lab, d3o is a soft and flexible material that hardens on impact. According to the manufacturer, d3o is produced by combining a viscous fluid with a polymer (both proprietary in nature). The molecules are weakly bound and move very slowly under normal conditions, making the material very soft and flexible. However, the distress of a sudden impact causes the chemical bonds to strengthen and the moving molecules to lock together. The material becomes a hard, protective shield. This process happens in less than one thousandth of a second. The faster the impact, the more rapidly the molecules respond.
