The smart diaper aims to (1) detect humidity, (2) be capable of sending real-time indication of the saturation to the healthcare workers when urine loss occurs and (3) generate alerts when the diaper requires changing. Potential benefits of the smart diaper compared to incontinence management products without sensor technology include: workload reduction, increased comfort for residents and staff, more person-centred care, increased quality of care, less skin damage and economic (e.g. less costs due to less excessive diaper changes), and/or environmental (e.g. less waste) gains.
