Shockwaves that are characterized by high pressure and strain rate with extremely short duration about nanoseconds cause blast-induced traumatic brain injury sustained by personnel exposed to shockwave-generating high-energy explosives. To protect the personnel novel approaches for shockwave energy dissipation (SWED) are in demand as conventional armor systems designed for ballistic protection do not provide sufficient mitigation. Recent works proposed that material-based energy absorbing strategies can be promising for effective SWED due to the tunable response time and high energy conversion/storage capability. Here, we present the research that seeks to develop approaches for efficient SWED in soft matters designed based on the availability of shock responsive chemical and physical reactions. Importantly, the shock-responsive materials can be exploited in other practical applications, including the measurement of adhesion strength and 2D surface patterning.
