Blog 5 - FFT & HRV

 

Week 7 Project Meeting

This week, we discussed a direction we would like to take the HRV sensor in. Using the programs we have created over the past few weeks; the aim is to create a system for monitoring the HRV sensor using the MicroBits.

 

What is Fast Fourier Transform (FFT)

Fast Fourier Transform is an algorithm that helps to identify what frequencies are in a signal. These signals can be anything from audio, communications and biomedical signals.

Slower heart rates happen when you're resting or relaxed, and faster rates happen when you're active, stressed or when you’re in danger.

 

What is HRV

https://my.clevelandclinic.org/health/symptoms/21773-heart-rate-variability-hrv

Heart Rate Variability is the fluctuation in variability between heartbeats. These variations are very small, adding or subtracting a fraction of a second between beats.

Blog 2 - HRV Demo

Lab 2 - Simple Heartrate Sensor Demo For the second lab, our task was to explore the capabilities of the Micro-Bit platform by connecting an external sensor to the microcontroller through its' GPIO pins. Readings were aquired through a simple serial read script created in Microsoft Makecode. In this case, the external sensor measures heart rate / pulse by shining a bright green LED light into skin tissue and measuring the light reflected back. As the heart circulates blood around the body, a small variation in pressure occurs within blood vessels, arteries and capillaries. This pressure variation can absorb more or less light at various stages of the heartbeat and is the primary mechanism of the HRV sensor. By detecting fluctuations in light reflected back from the body, it is possible to get an acurate reading on our heartbeat. A similar mechanism of measuring bloodflow is used in other 'smart' technology such as smart watches, fitness bracelets and even in professional me...

Week 1: HRV Review

  What is it? Heart rate variability (HRV) is the measure of the variation between heartbeats. It is controlled by your autonomic nervous system (ANS). This system operates automatically and regulate process such as the heart rate and other bodily functions that are are not under conscious control. This system is broken into two branches the flight or fight (which preparing the body for action and stress) and the rest + digest (which promotes relaxation + recovery). HRV is influenced by the ability to smoothly shift between these two branches.  High HRV: Larger difference between successive heartbeats - Indicates a more flexible and adaptable autonomic nervous system.  Low HRV: Smaller differences between successive heartbeats - Indicates a less flexible autonomic nervous system.                                                ...
