Abstract:
A non-powered impact recorder is disclosed. The non-powered impact recorder includes a resonator tuned for a resonant response within a predetermined frequency range. A reduced cross-sectional area portion is formed within the resonator and configured to structurally fail when the resonator experiences the resonant response. Additionally, the non-powered impact recorder includes an electric circuit element disposed about the reduced cross-sectional area portion of the resonator. Upon structural failure of the resonator, the electric circuit element is broken to cause a discontinuity in the electric circuit element. Interrogation of the discontinuous electric circuit element facilitates approximation of impact frequency and/or impact energy.
