Wearable Technologies Design Czero Reducing Viral Infections by Sophia Neill Czero is a wearable device that vibrates when the users hand is near their face, reminding them not to touch it, reducing transmission of contagious infections notably. Not only does this device break the dangerous habit of touching their face, it also tracks the state of the user and informs them when they may have contracted an infection. To have this information readily available to every individual user, the actions needed to recover or isolate will happen at the early stages of the illness, mitigating the spread in the most efficient way possible.
