Abstract
A pressure sensor for a toothbrush. The pressure sensor includes a substrate, a contact arm in the substrate, a power source, a signal element, and a sensor contact. The sensor contact may be mounted to the substrate such that the contact arm is not in contact with the sensor contact when the substrate is not flexed. As a user applies pressure to a toothbrush head, the substrate can flex and move the contact arm toward the sensor contact. When a threshold force is applied to the toothbrush head, the contact arm can contact the sensor contact, completing a circuit between the power source, the sensor contact, and the signal element that activates the signal element. A second sensor contact can be mounted to the substrate opposite the first sensor contact. The second sensor contact can allow the signal element to indicate three different states to a user.
