Abstract
The all-directional fall sensor of the present invention includes a first casing defining a first interior space filled with a liquid and a floater buoyed by the liquid inside the first casing. The floater includes an indicator having indicative materials therein. The indicator includes a body defining a chamber, which is divided into at least a first portion and a second portion with a first sealing member located therebetween. The indicative materials are contained in the second portion of the chamber and are sealed therein with the first sealing member. When the all-directional fall sensor is applied with a force, the first sealing member would be dislocated and thus the indicative materials are dispersed within the chamber.
