An apparatus for personal health maintenance has a sensor attached at least indirectly to a carrier member in turn attachable to a user or subject and configured for measurement of at least one physiological parameter of the user. A reservoir contains a preselected composition. An electronic processor is operatively connected to the sensor for receiving a signal therefrom encoding a measurement of the physiological parameter, the processor being configured for determining a divergence of the physiological parameter from a predetermined magnitude, the processor being operatively connected to a dispensing mechanism for ejecting, from the reservoir, an amount of the composition to be administered to the user to reduce divergence of the physiological parameter from the predetermined magnitude. The dispensing mechanism includes an expandable polymer composite layer with gas-filled micro-bubbles or microspheres expandable by operation of a heating element.
