1. A finger-wearable blood pressure monitoring device, comprising:
a cuff;
a bladder disposed proximate to the cuff;
a pressure sensor coupled to the bladder to detect pressure changes within a digital artery of a finger due to blood flow when the finger wears the finger-wearable blood pressure monitoring device, wherein the bladder extends partially along a circumference of an inner surface of the cuff and is disposed between the pressure sensor and the finger when the finger wears the finger-wearable blood pressure monitoring device, and wherein the pressure sensor is disposed on the inner surface of the cuff; and
control circuitry coupled to the pressure sensor to receive pressure data representative of the pressure changes and determine a blood pressure based on the pressure data.
