Summary:Methods and devices for a miniature, ultra-low power impact recorder for detecting, quantifying and recording the energy of an explosive blast or ballistic projectile impact. In one embodiment, the impact recorder can included a sensor comprised of an array of electromechanical resonators that is sensitive to the vibrations produced in selected, discrete frequency ranges that approximate the spectral signature characteristics of the shockwave resulting from the ballistic impact event, even after traveling through impacted material or body tissues.
