Band tightness sensor of a wearable device
First Claim
1. A wearable device, comprising:
- a housing including a processing unit and a health sensor;
a band operable to couple the housing to a body part of a user; and
a tightness sensor, coupled to the band and communicably coupled to the processing unit, that produces a signal indicating a tightness of the band;
wherein the processing unit is configured to;
determine the tightness of the band using the signal; and
if the tightness of the band is outside a range of tightness values, provide output directing the user to adjust the band to improve operation of the health sensor;
wherein;
the tightness sensor comprises first and second capacitive plates operable to change proximity with respect to each other in response to a change in the tightness of the band; and
the signal indicates a capacitance between the first and second capacitive plates.

Abstract
A wearable electronic device has a processing unit and a health sensor included in a housing, a band operable to couple the housing to a body part of a user, and a tightness sensor coupled to the band. The tightness sensor is operable to produce a signal indicative of a tightness of the band on the user'"'"'s body part. The processing unit determines a tightness of the band based on the signal and perform one or more actions based thereon. Such actions may include evaluating the signal for changes in the tightness of the band according to operational tolerances of the health sensor, providing output directing the user to adjust the band to improve operation of the health sensor, monitoring changes in the tightness of the band and adjusting a measurement obtained by the health sensor, and so on.
