US 2024/0330637 A1 · IMPACT INDICATOR

Abstract

An impact indicator includes a microelectromechanical system (MEMS) device comprising an element movable from a first position to a second position in response to receipt by the element of an impact event. The MEMS device further comprises a first circuitry configured to change from a first state to a second state in response to movement of the element from the first position to the second position where the first circuitry is prevented from returning to the first state in response to changing to the second state. A second circuitry is coupled to the first circuitry and is configured to output a value indicating that the element is in the second position. An activator element configured to maintain the element in the first position until removal of the activator element from the MEMS device.
