A 3D-printed, touch-activated, sanitizer dispensing device for reducing healthcare-acquired infections


Aim: We present a touch-activated, sanitizer dispensing (TSD) device, intended to be mounted on high-touch surfaces, that aims to reduce nosocomial infections. It disinfects the person’s hand touching its surface while being self-sterilizing. Materials & methods: The TSD device consists of an array of 3D-printed, passive, miniaturized, mechanical valves that dispense a small amount of liquid sanitizer when touched. Its mechanical performance and disinfecting efficiency were quantified using simulations and experimental tests. Results & conclusion: The TSD device has a...
