This concept paper describes a device consisting of a disinfectant wristband for the hands of the wearer and objects that the wearer intends to touch. This wristband can be powered automatically by the movement of the user’s hand or by solar cells or, if necessary, by a power outlet. It disinfects the surface of the hands and the objects in front of them using an ultraviolet (UV) lamp. Control and monitoring can be carried out automatically or manually, which guarantees complete and effective disinfection. The electronic control system, which is fully integrated into the UV emitter head, regulates the intensity and duration of the UV radiation and also manages the electrical energy. In addition, the wristband can be fitted with an optional watch to improve its decoration and ergonomics. The device in question has a compact, elegant, and practical shape. This hand sanitizing wristband can be an effective tool in the fight against the current COVID-19 pandemic and, in general, help to address the health challenges related to hygiene and disease prevention.
