A new anti-assault device for women wards off potential assailants with an 80,000-volt electric shock.
Dubbed "exo-electric armor," the No-Contact Jacket looks like an ordinary fashionable women's coat. But an inner layer of conductive fiber carries a low-amp charge that delivers a nasty but non-lethal shock to anyone who messes with its wearer.
"It's kind of like sticking your finger in a wall socket," said Adam Whiton, one of its designers. "It hurts. If someone tries to grab you from behind, they get the full, hefty shock out of it. That's really painful."
Designed by Whiton, an industrial designer at the Massachusetts Institute of Technology, and Yolita Nugent, head designer at Advanced Research Apparel, the jacket is intended to be an alternative to handguns, pepper sprays and rape whistles.

Unlike weapons and sprays, the jacket can't be grabbed from a woman and used against her. And it's not as lethal as a gun.
"We initially thought the idea was a little extreme," said Whiton. "But we got a lot of positive feedback. It defends, it protects and it gives confidence to women. By encasing the whole body in this electric fence, it forms a barrier that people just shouldn't enter into."
The jacket is made from Aracon, a conductive fiber developed by DuPont, which is sandwiched between an inner rubber lining which protects the wearer from shocks and an outer layer of waterproof nylon.
Powered by a regular 9-volt battery, which builds a high-voltage but low-amp charge through a series of step-up circuits, the jacket uses technology similar to the circuitry in stun guns and bark-deterring dog collars. While the charge is enough to deliver a jolt, it won't kill anyone, Whiton said.
To prevent accidental discharges, the wearer must arm the jacket before it can deliver a shock. A lock on the sleeve must first be opened with a key, and then the charge is built up by holding down a button inside one of the sleeves.
The idea is to charge it only in threatening situations or when the wearer feels vulnerable, Whiton said. A woman might arm it when she's walking to her car at night, for instance.
When charged, the jacket crackles audibly. A pair of slits in the outer lining shows the electric arcs that course across the entire middle layer. It's an impressive display of the jacket's power.

When charged, the jacket sparks and emits an "evil" crackling sound.
Whiton said the "really evil crackling sound" makes him flinch involuntarily: The shocks he received testing the jacket conditioned him to associate the sound with pain.
The jacket is designed for women only. Its small size and narrow armholes are intended to prevent men from using it as an offensive weapon. Whiton conceded that women could use it offensively, and that it would be hard for police to arrest anyone wearing one.
Three female volunteers currently are testing prototypes in the field. The designers plan to put it into limited production by the end of the year. It should cost around $1,000. They are approaching apparel manufacturers who might mass-produce it and thereby lower the cost.
