Heart Rate Monitor
Heart Rate Monitor is a scholarly work, published in 2024. The main subjects of the publication include computer science, remote patient monitoring, and heart rate variability. It is crucial that humanity produces clean energy from any source possible in order to reduce the authors' reliance on unsustainable power sources like lithium ion batteries and electricity generated by the burning of coal or fossil fuels.Many small devices are powered by batteries, which can only be reused so many times before they are defective.The mining required for their production is also responsible for many environmental and human rights problems.Consequently, the authors' group has decided to produce a heart rate monitor, which is powered by the user's body heat.We used thermoelectric generators, which consist of panels with two metal-semiconductor sides that generate energy through the transfer of electrons.This is a free and clean energy source as it makes use of thermal energy that would otherwise be wasted.the authors' design consists of a chest strap, which the thermoelectric generators and an Arduino are attached to.The heart rate monitor is also wired to the Arduino, and straps onto the finger of the user.These are wired to the computer where the heart rate and voltage output are displayed.The thermoelectric heart rate monitor (THRM) serves as a proof of concept that could eventually be modified into a marketable product.Constraints such as time and money limited its wearability and efficiency.These could be improved in the future with better materials, wiring and code.The Thermo-Electric Generator (TEG) do not power the heart rate monitor directly in the authors' final product.The TEGs feed power to the computer which powers the heart rate monitor.the authors' hope is that eventually the authors' product could be modified to be powered directly from body heat without relying on other power sources.Later designs would also have a more streamlined appearance and would use more efficient TEGs to generate larger amounts of electricity.
