Sensor cable makes life difficult for burglars

Ideally, homeowners want to be warned if a burglar sneaks onto their property, and farmers want to know if horses or sheep are no longer in the paddock or field they were left grazing in. Experimental physicists at Saarland University have developed a flexible security solution that can be used in gardens, driveways, business premises, or on grazing land and in woodland. The sensor cable system that Professor Uwe Hartmann and his team have developed issues a warning signal indicating if and wher
