Disclosed is an impact-responsive vest having a piezoelectric layer sandwiched between other layers and connected by wire leads to a control module. The control module includes a programmable read-only memory having parameters identifying, through the amplitude of a signal impact, forces produced by paint ball impacts which are compared with impact signals from the vest. When a match is found, the compare circuit sends a signal to an audible alarm to alert the wearer that he or she has been hit by a paint ball. The control module is compact and is worn by the vest-user. Also disclosed is a remote reset module to provide a reset signal to the control module once the alarm has been activated.
