This report outlines the design procedure and outcome of the production of the iBeat - Temperature Sensing BPM Monitor.
Although there currently exist devices that monitor body temperature and heart rate, these devices are mutually exclusive. There exists the potential to develop a device that cohesively combines these sensors into one package. This was seen as important as medically, there exists a relationship between human heart rate and surface body temperature.
It has been observed that as the human body core temperature rises, surface temperature also rises. This is due to a physiological need to reduce the core body temperature, restoring homeostasis. The human body achieves this by way of vasodilation - dilating peripheral veins to help radiate heat away from the body, cooling it down. The consequence of dilating these vessels is an associated drop in blood pressure due to the increased volume available within the blood vessels, compared to the volume of blood flowing through them. For the body to maintain a relatively constant (and safe) blood pressure, the heart must pump blood at a higher rate, thus increasing the heart rate of the patient.
This relationship is readily observed among athletes and people undergoing strenuous physical activity. The iBeat - Temperature Sensing BPM Monitor will allow for easy access of this data so that patients and clinicians can use it to monitor these parameters.
In development of the iBeat - Temperature Sensing BPM Monitor, many aspects of medical sensor design were traversed. An understanding of the small signals involved and their necessary filtering and amplification before being able to use was garnered. In following a methodical approach to design and testing, a non-invasive, simple and intuitive device was created. Its’ low power consumption, coupled with optimised code allows for quick analysis of the physiological parameters of temperature and heart rate. Being able to function across a host of mobile and PC operating systems only serves to increase its appeal.
