Abstract
A wire-less dart adapted to be projected by a gun and capable of applying an electrical pulse of sufficient energy to stun a target. The dart includes a photovoltaic cell responsive to a coherent electromagnetic energy source, such as a laser, for converting the beam energy to an electrical pulse. The dart also includes a pair of barbs extending from its distal end which penetrate the target's skin to a non-injurious depth. These barbs serve as electrodes and deliver the electrical pulse to the target. The projector, such as a gun, includes a pulsed laser light source which is aimed at the same location as the projector. Accordingly, the laser source focuses the pulsed laser energy source upon the dart PV cell. The projector includes a propellant sufficient to launch the dart, but with only enough kinetic energy such that the dart barbs penetrate the assailant's skin. The device has a long operating range.
