1. A patch device comprising:
a photoplethysmography (PPG) sensor comprising at least one light emitting diode (LED);
a seismocardiography (SCG) sensor comprising a three-axis sensor;
an adhesive layer configured to adhere to skin of a chest of an individual;
one or more rigid components connected to the adhesive layer, the one or more rigid components comprising a hardware processor for communication with the PPG sensor and the SCG sensor, the hardware processor configured to receive a plurality of measurements from each of the PPG sensor and the SCG sensor; and
an air gap between a lower surface of the adhesive layer and a lower surface of the PPG sensor for providing a compressive downward force when the adhesive layer and the PPG sensor are in contact with the skin of the chest of the individual, thereby improving signal quality of the PPG sensor, wherein:
the PPG sensor passes through the adhesive layer;
the adhesive layer and the PPG sensor are configured to be in contact with the skin of the chest of the individual simultaneously with at least a portion of the air gap therebetween.
