Electronic Alarm Cloth
"At first glance, a cloth bag may seem an unlikely security device. But if it's made from a new, electronic fabric, it could not only resist tampering, but sound off an alarm or send an alert to the owner and authorities."
It is made of conductive fibers and can include a lot of different sensors and technologies. The range of potential products is huge but this article focuses on security solutions mostly. Patent is pending till end of june though.
