The COVID-19 pandemic created additional emphasis for medical staff to sanitise the surfaces they work on. Non-clinical digital devices often went under the radar due to the increased time pressures on medical staff, however, they can harbour just as much - if not more, bacteria than a flat surface due to the large surface area, number of crevasses and consistent use between several medical staff. Devices are required to be sanitised before and after use, however this is rarely done and if it was, staff never knew how well or recently it was done, creating anxiety.
These sanitisation indicators make use of a smart material that becomes transparent when wiped with an anti-bacterial cloth and gradually returns to white as the cleaning solution dries off, indicating the device needs to be sanitised again. The indicators can resist abrasion from anti-bacterial wipes, cost no more than 0.8p and can be adhered to several devices such as keyboards, tablets and phones. The development of this product has provided opportunity to be scaled in to education and hospitality sectors.
One wipe is all it can take, be clear on device hygiene.
