Abstract

Traumatic brain injuries can cause permanent damage to the brain, leading to concussion and memory loss. As shown on page 6041, S. Yang and co‐workers have developed a power free, light weight, and highly sensitive polymer‐based inverse opal as a mechanochromic sensor that changes color upon impact with pressures in the MPa range. Depending the amount and rate of applied force, the colour change is permanent, so the impact can be determined without complicated in situ optical experiments.
