Open platform, eight-channel, portable bio-potential and activity data logger for wearable medical device development
The design of a wearable, portable and reconfigurable physical activity and an eight-channel bio-potential data logger, capable of increasing compliance by enabling customised feedback (i.e. calories expenditure and amount of physical activity) is presented while recording clinically meaningful information regarding a subject's health. Here an application of the device to the cardio-vascular system comprising simultaneous recording of ECG and activity in both resting and under-stress conditions is presented (clinical trials are performed under the supervision of expert cardiologists at Prince of Wales Hospital NSW, Australia). The designed device (based around the low-power LPC1768 ARM processor and the bio-potential front-end ADS1298) is an open-source one and is provided under the GPL GNU 3.0 collaborative licence.
