1. A trigger mechanism comprising:
- sensing electronics;
a power source;
a length of bifilar wire comprising two electrically conductive filaments separated by an insulator, the bifilar wire having a first end in electrical connection with the sensing electronics and the power source and a second end which is free;
wherein the sensing electronics are configured to monitor the status of a circuit created between the bifilar wire, sensing electronics and power source when two filaments of the bifilar wire are fused or joined together at a section along the length of the bifilar wire.

Abstract
A trigger mechanism including sensing electronics, a power source and a length of bifilar wire. The bifilar wire has two electrically conductive filaments separated by an insulator, with a first end in electrical connection with the sensing electronics and the power source and a second end that is free. A circuit can be created by fusing together the two filaments in a section of the bifilar wire. The sensing electronics are configured to monitor the status of a circuit created between the bifilar wire, sensing electronics and power source and to output a signal when the circuit is broken.
