Abstract
A facemask includes a facemask body, a plurality of electrical contacts and a control circuit. The facemask body has an end including an opening and a skin contact perimeter extending along a periphery of the opening, with the skin contact perimeter configured to sealingly engage with a user's face. Each electrical contact is disposed at a respective region of the skin contact perimeter, and each electrical contact is configured to sense when the respective region of the skin contact perimeter is sealingly engaged with a user's face. The control circuit is disposed on the facemask body, and the control circuit is configured to receive a signal from each electrical contact when the respective region of the skin contact perimeter is sealingly engaged with a user's face and to initiate output of an audible stimulus and/or a visual stimulus in response to receiving a concurrent signal from all of the plurality of electrical contacts.
