Aerosol-generating system comprising a health monitoring device

An aerosol-generating system, comprising:

• a health monitoring device comprising:
• at least one sensor configured to collect health data from a user,
• a controller configured to
• receive the health data collected by the at least one sensor, and
• determine a health parameter based on the health data, and
• a health monitoring device power supply configured to supply electrical power to at least one of the controller and the at least one sensor, the health monitoring device not being an aerosol generator for generating an aerosol from an aerosol-forming substrate;
• an aerosol-generating device comprising:
• a cavity configured to receive a plug of tobacco,
• an aerosol-generator configured to generate aerosol from the plug of tobacco, and
• an aerosol-generating device power supply configured to supply electrical power to the aerosol-generator,
• wherein the health monitoring device and the aerosol-generating device are separate devices;
• and
• a charging unit comprising:
• at least one cavity configured to receive the health monitoring device and the aerosol generating device, and
• a charging unit power supply,
• wherein the charging unit power supply is configured to transfer electrical power from the charging unit power supply to the health monitoring device power supply when the health monitoring device is received within the at least one cavity,
• wherein the charging unit power supply is further configured to transfer electrical power from the charging unit power supply to the aerosol-generating device power supply when the aerosol-generating device is received within the at least one cavity,
• wherein the at least one cavity is a single cavity configured to receive each of the health monitoring device and the aerosol-generating device,
• wherein the single cavity is sized to receive only one of the health monitoring device and the aerosol-generating device at a time,
• wherein the charging unit power supply is configured to transfer electrical power from the charging unit power supply to the health monitoring device power supply when the health monitoring device is received within the single cavity, and
• wherein the charging unit power supply is configured to transfer electrical power from the charging unit power supply to the aerosol-generating device power supply when the aerosol-generating device is received within the single cavity.
