1. A blood pressure measurement device comprising:
a cuff configured to extend around an arm of a user, the cuff comprising an inflatable bladder;
a pump;
a piezoelectric sensor coupled to the cuff;
a capacitive sensor coupled to the inflatable bladder; and
a processing unit operably coupled to the piezoelectric sensor and the capacitive sensor, the processing unit configured to;
determine, at least in part based on a signal generated by the capacitive sensor, that the blood pressure measurement device is in an on-arm state;
in response to determining the blood pressure measurement device is in the on-arm state, cause the pump to inflate the inflatable bladder; and
after the inflatable bladder is inflated to occlude a blood vessel of the user, while the bladder is deflating, and based at least in part on a signal generated by the piezoelectric sensor and responsive to blood flow in the arm of the user, determine a blood pressure of the user.
