摘要：
Embodiments of the invention include a wearable blood-pressure monitor and methods of forming such devices. In an embodiment, the blood-pressure monitor includes a stretchable substrate. Additionally, a semiconductor die may be embedded within the stretchable substrate. In order to determine blood-pressure, the blood-pressure monitor may include an electrocardiogram sensor and a piezoelectric sensor for detecting a ballistocardiograph response. In an embodiment, both types of sensor may be electrically coupled to the semiconductor die. Embodiments of the invention include a piezoelectric sensor that includes a piezoelectric layer and a first and second electrode. In an embodiment the first electrode is in contact with a first surface of the piezoelectric layer, and the second electrode is in contact with a second surface of the piezoelectric layer that is opposite to the first surface.
