A variety of device constructs are contemplated in the wearable sensing devices of the present invention, each of which facilitate the monitoring of physical and physiological parameters in humans. Wearable sensing devices are incorporated into a wearable and comprise a small portable power supply; monitoring electronics mounted to or used in the wearable; a processing unit or component; and a memory unit or component to continuously or intermittently record parameter data—such data then being stored in an onboard portable memory unit and/or wirelessly transmitted to another electronic device or devices. The wearable sensing device incorporates a wireless data transmission unit or component to link to a personal computing device. The memory unit can be synchronized with the processing unit to save and then later download monitoring data for detection of any physical or physiological condition that is benign or a condition that requires mediation of some sort.
