Abstract: An impact indicator includes a micro-sensor having a mass element configured to move from a first position to a second position in response to receipt by the mass element of an impact event. The micro-sensor includes detection circuitry configured to change from a first state to a second state in response to movement of the mass element from the first position to the second position. The detection circuitry is prevented from returning to the first state in response to changing to the second state. A radio-frequency identification (RFID) module is coupled to the detection circuitry and is configured to output a value indicating that the mass element is in the second position. An activator element is configured to maintain the mass element in the first position until removal of the activator element from the micro-sensor.

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.
