Andre Broekman, a Civil Engineering PhD candidate at the University of Pretoria, has developed touch-sensitive concrete — a technology that could transform home and business security in South Africa.

This could reduce the need for electric fencing, allowing South Africans to protect their properties and businesses with an invisible solution. The technology also has the potential to replace internal alarm systems by implementing it in the flooring of a building.

Broekman explained that the technology could also be used to aid the visually impaired. His prototype keyboard has tactile concrete keys engraved with symbols.
