Impact indicator
Abstract:
According to one aspect of the present disclosure, a device and technique for impact detection and indication is disclosed. The impact indicator includes a first member having a reservoir for holding an indicator fluid; a second member couplable to the first member; and a disc member disposed at least partially between the first and second members and extending over the reservoir. A capillary gap is formed at an interface between the disc member and a surface of the first member facing the disc member. Responsive to receiving a predetermined level of impact, the indicator fluid moves from the reservoir to the interface between the disc member and the first member and wicks into the capillary gap via capillary action, the indicator fluid disposed within the capillary gap providing a visual indication of the received predetermined level of impact.
