#2311: Heartaser

Today’s invention is a personal defence system for those who have already suffered some kind of heart problem.

This takes the form of a sub-cutaneous defibrillator with an additional two electrodes facing outwards just beneath the skin.


If a user of such a system is grabbed by an assailant, he or she would give them a bear hug or divert their hand onto the skin over the embedded unit.

This pressure would activate a switch which sets up a sudden voltage between the outward facing contacts (without disrupting the heart of the wearer of course).

A voltage of about 2kV would thus be applied across a small area of an attacker’s body…quite enough to discourage any further aggression.
