Product Details

This is a hook and loop mechanism (commonly also known as conductive Velcro®) that conducts electricity. You can see in the picture (on the photo of the sample), the electricity is running through the two pieces stuck together and lighting the bulb. It is manufactured using woven nylon material impregnated with silver.

This fastener is perfect to integrate into smart fabrics and other soft-goods products (clothes, stuffed animals, back packs) where you want to incorporate a soft switch. For example, your backpack could set off an alarm if someone opened the flap to get at the contents inside; or your winter jacket could turn on its built in heater when you closed the flap in front.

In addition to soft switches, this material is also perfect for anti-static applications. In clean room and electronic assembly plants, production workers must always wear a leash around their arm or leg with a wire connecting them to “ground.” With this conductive fastener they could more easily connect and disconnect.

The US military is one of the largest users of this material. They use it in tents and other equipment to shield their electronics from stray radio frequencies.

FAQ

How does the conductive hook and loop work for RF shielding?

Products that release radio frequencies need to be coated with nickel, silver, copper or a combination of these to prevent interference with other products’ radio frequencies. Conductive hook and loop has the ability to shield RF because it is impregnated with silver.

How could it be used to prevent static electricity buildup?

A second type of conductive hook and loop is made conductive by carbon loading. It is less conductive and less costly than silver-impregnated conductive hook and loop. It is used to discharge static electricity in one’s body. Clothing that contains this type of hook and loop collects the static electricity at the end of the loops and discharges to the air. This type of conductive hook and loop is marketed by Antistatic Industries (see vendors on left).

Please describe the innovation in this technology.

This hooks are made by combining woven nylon tape with napped nylon hooks and impregnating with silver. A second, less conductive variety of the tape is made by adding carbon to the material (carbon loading).

Please provide some general information about this technology.

The conductive hook and loop is mostly used for RF shielding applications such as fasteners and holding parts together within products. In addition using it to seal products or containers for RF shielding is a common use. The military is the largest consumer of conductive hook and loops for this reason.

What is the reason this technology was developed? Or What need does this technology solve?

Typically, conductive hook and loop is mostly used for RF shielding applications in the military. It can be used in computers, electronics, military gear or tents to shield from radio frequencies.

However, in our own tests it conducted well enough to be used as a switch. This makes possible a whole range of applications yet to be explored.
