1. A patch device, comprising:
a plurality of flexible layers comprising:
a silver layer;
a dielectric layer; and
a printed circuit board layer;
a photoplethysmography (PPG) sensor comprising:
an array board with a plurality of light emitting diodes (LEDs); and
an adaptive filter configured to reduce a noise of readings from the array board;
a seismocardiography (SCG) sensor comprising a first analog to digital converter and a three axis sensor;
an adhesive layer configured to adhere to skin of a chest of an individual, wherein:
the PPG sensor passes through the adhesive layer;
the PPG sensor is configured to be positioned over the chest of the individual through the adhesive layer; and
an air gap between a lower surface of the adhesive layer and a lower surface of the PPG sensor is less than 1.1 mm; and
one or more rigid components connected to the plurality of flexible layers, the one or more rigid components comprising at least one computing device comprising a hardware processor electrically wired for communication with the PPG sensor and the SCG sensor, the at least one computing device configured to receive a plurality of measurements from each of the PPG sensor and the SCG sensor, wherein:
the adhesive layer and the PPG sensor are configured to be in contact with the skin of the chest of the individual simultaneously with the air gap therebetween; and
the PPG sensor is mechanically strain isolated from the one or more rigid components.
