Sensing contact force related to user wearing an electronic device
First Claim
1. A wearable electronic device, comprising:
- a watch body;
a back plate coupled to the watch body;
a band coupled to the watch body and configured to attach the watch body to a body part of a user;
a force sensor, coupled to the back plate, configured to produce a force signal using a force exerted between the body part of the user and the back plate, the force sensor positioned between the watch body and the back plate, wherein the back plate is coupled to the watch body via the force sensor; and
a processing unit, communicably coupled to the force sensor, configured to determine a tightness of the band using the force signal received from the force sensor.

Abstract
A wearable electronic device includes a body, a housing component, a band operable to attach the body to a body part of a user, and a force sensor coupled to the housing component. The force sensor is operable to produce a force signal based on a force exerted between the body part of the user and the housing component. A processing unit of the wearable electronic device receives the force signal from the force sensor and determines the force exerted on the housing component based thereon. The processing unit may use that force to determine a tightness of the band, determine health information for the user, adjust determined force exerted on a cover glass, and/or to perform various other actions.
