Heart rate detection assembly and methods of detecting a heart rate

A system to identify a signal-to-noise ratio of a plurality of heart sound waves within a vehicle seat, the system comprising:

• a sensor positioned within a cavity of the vehicle seat;
• at least one fluid medium positioned within the cavity;
• and
• at least one deflector member positioned within the cavity, the at least one deflector member at least partially surrounding the at least one fluid medium such that the at least one deflector member is configured to constrain and direct the plurality of heart sound waves through the at least one fluid medium to the sensor when an occupant is positioned within the vehicle seat, the at least one deflector member is configured to selectively deform to channel the plurality of heart sound waves to the sensor;
• at least one actuation device positioned within the cavity;
• a processor communicatively coupled to the at least one actuation device;
• and
• a non-transitory, processor-readable storage medium in communication with the processor, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the processor to:
• obtain the signal-to-noise ratio of the plurality of heart sound waves,
• determine that the signal-to-noise ratio is not at a predetermined threshold, and
• in response, actuate the at least one actuation device to deform the at least one deflector member.
