Touch-sensitive concrete was invented by Andre Broekman, a Civil Engineering PhD candidate at the University of Pretoria, and might revolutionize home and business security in South Africa.
Broekman demonstrated the concept in his concrete macro keyboard prototype. The technology essentially uses a touch breakdown sensor to measure changes in the capacitance over a concrete medium.
The technology could be used in home and business security solutions, removing the need for equipment such as electric fencing and alarm systems.
Wynand Steyn, head of the Civil Engineering department at the University of Pretoria, told MyBroadband that it could be adapted to send an alert — to you or your security services — as soon as someone touches your boundary wall.
