Dear Scott, I am a physician, and I noticed that the electrocardiogram displayed in your video is full of interference and noise. The isoelectric line does not remain stable at 0 volts, likely due to muscle contractions in your arms during the test. As a result, you are simultaneously recording an electromyogram along with the electrocardiogram. Despite this, it is possible to distinguish the spike of cardiac contraction from the noise. Additionally, if you are otherwise healthy (besides your love for complex electronic circuits), you should not have a 92% arterial oxygen saturation at rest. Therefore, the oximeter sensor probably needs calibration. This is my first time commenting, but I would like to express my congratulations on all your videos. Each one is an educational gift to those of us who dabble in electronics as a hobby. Please continue your high-quality work, and it would be my pleasure to assist as a doctor in any application related to my field. Kind regards, Dimitrios

Agreed, that's an extremely noisy ECG. Coming at it from the biomedical engineering side here. Have not read the datasheet in detail. Would be surprised if it didn't offer more signal conditioning features onboard. Probably designed with a downstream DSP in mind. I've cobbled together entire frontends on a breadboard or two before. Consistently impressed by modern semiconductors.

As a person who works with ECG signals (mostly writing code that processes signals from wearable ECG recorders), the last demo showed basically a bunch of noise and almost nothing of substance. I saw a comment saying that You should add other electrodes and I agree because this signal is awfully reminiscent of what happens when one of the electrodes gets disconnected when using a virtual ground for ECG. For people who are more interested in the details, You can somewhat make out the R peak in the data but the T wave is so large (greater than R) that it is impossible due to heart physiology, T wave is the relaxation of the heart muscle and it is usually about 1/3rd of the height of R, and the P wave is also nonexistent which also should be impossible because that's the signal that starts the muscles moving in your heart.

@daviddavidson2357Ай бұрын
I was thinking the same thing. Never did biology above undergrad level, but I couldn't make out any readable waveform other than a heart rate. Probably because it's measured at the fingertips, which isn't really ideal as the distance makes the signal weaker and nerves along the way create noise. Kind of like hooking EEG electrodes to your testicles and expecting to see brainwaves on the monitor. Maybe the inputs for actual electrodes do better though.
@aymenninja8120Ай бұрын
@@daviddavidson2357 yes the location of the electrodes and also the number of electrodes, the heart don't get all electrically excited then goes down like a lamp and a switch. different heart parts gets excited at different times, and they must do that in a harmony. ECG is not a diagnostic tool to just see if a person is alive or dead, it is essentially used to see if the person heart is in harmony or not, thus you can't measure just one potential difference and call it ECG, you have to measure many potential differences at the same time. hence comes the PQRST waves. if the aim was to just see the heart rate it is fine to use two electrodes only, if the aim is to get detailed information no, for a cardiovascular doctor it would be like listening to part of a conversation and you fill the gaps.

Hello Scott! I work in the medical device industry and so glad you have tested some biomedical electronics stuff! A couple of comments: 1. 92% SpO2 is far from normal. You'd expect a >95% on a normal, healthy adult. During resting state this value should be at >98% in most cases. (Remember during Covid times patients with an SpO2 value below 88% were considered critical and would require assisted ventilation.) As of the PPG waverform morphology it does make sense - the drift in the signal amplitude is likely caused by slow finger movements as suggested by the envelope of that signal. Actural SpO2 devices would normally feature a clip with the photodiode and LEDs (Red and IR) on either side, in order to a) limit the "volume" in which blood would circulate, and b) block ambient light to minimise interferences, so that changes in the oxygenated haemoglobin vs. deoxygenated can be calculated. This is a classic application of the Beer-Lambert law. 2. The ECG graph does not resemble anything like an actural ECG signal. Granted, you may think of the peaks as R-waves, but the waveform does not seem well-processed. ECG standards such as IEC 60601-2-25 and AHA clinical recommendations call for a high pass filter with a cutoff frequency at 0.05-0.5 Hz, a low pass filter at 150 Hz, and a mains notch filter at 50 or 60 Hz. The HPF is there to remove the baseline wander and respiratory signals, while the LPF for removing EMG from muscle contractions. It seems that the EMG from flexing your fingers are drowning the ECG signals from your plot. Maybe worth another try with stick-on electrodes, preferrably three of them, on the left arm, right arm and left leg. If this eval board comes with built-in right-leg driver circuit then you are in luck as it will greatly reduce the mains interference on your ECG signal, if you also connect another electrode on the right leg to the output of this circuit. It will invert the mains interference signal and re-inject it to the body, works like an active noise cancelling headset. 3. Electric safety is always an essential performance in medical devices. The electrodes you've touched are effectively type BF applied parts of a medical device (per IEC 60601-1). Hence it is required to have those galvanically isolated from the PSU (in this case, a laptop connected to mains). This can be satisfied if you insert a USB isolator with more than 2kV dielectric strength between its primary and secondary sides between the laptop and the eval board, OR disconnect the laptop from its charger and use a battery pack to power the eval board, if necessary. As always, very informative video! And I will see you next time! 😊

It would be much more expensive and time consuming if the engineer had to find out all those things about the sensor himself.

The ECG tracing does not resemble an actual ECG. I think that the problem is that the board doesn’t have any filters to eliminate all the noise. Try applying a band pass filter with a low pass @ 150 Hz and a high pass @ 0.5Hz. Additionally, you want to eliminate the power interference by applying a notch filter and blocking the frequency of your mains power (50Hz in Europe, 60Hz in USA). That should clear the noise and leave the normal ECG tracing showing the P-QRS-T waves.

I am an Electrical Engineer working in the Medical Devices field and I have designed EKG machines before. I agree with what the others said that what you have likely seeing is muscle noise. That is what an EKG system is designed to detect since the heart is just a big muscle. The challenge with using EKG from just a single pair of fingers is that there are a lot of muscles that are much closer than your heart That is why EKG system measure across the body. There single limb heart rate sensors typically use pulse oximetry. They use light to detect the cyclic change in oxygen levels that are caused by your heartbeat. They often do this by comparing the transmission or reflection of blue and red light. I will have to check out the chip it uses. I wonder how cheap I could make an EKG system now. There are some possible applications for this if they could be cheap.

Hey Scott, I have a Card10 badgefrom the CCCamp 2019(an electronics "dev" board given out at conferences), which has an ECG sensor as well, and the trick to taking good measurements using these tiny devices is calibration and being very still. The calibration(for what I guess are filters) on (at least my) devboard is handled by the front-end chip automatically, and takes a few seconds(up to 30), but you can clearly see when the data becomes "filtered". Maybe you'll even get some extra parsed data then. Any type of movement will probably give you a noise spike in the data and might interrupt calibration, so try to remain still. And good contact also helps, my badge needed to be pressed quite firmly to get a good reading. You can identify a good reading mostly by it looking like one of those TV heart monitors that go beep-beep(You know what I mean, right? :P).

Regarding EDA, usually, the signal is filtered and processed to detect rate of changes. In conjunction with other signals (like ECG) it becomes a good indicator of changes in emotions, so smartwatches use it to detect stress, unrest, etc. As far as I have read, the main issue is that the patterns are highly individual-dependent. So currently smartwatches/phones train a machine learning model with your data for about two weeks (inviting you to also label events, i.e. indicate how you were feeling in certain identified "events"), so they can eventually identify these events automatically. I guess this is the reason you don't see any useful data in the DevKit, it would have to implement a detection technology and then train it with a bunch of data first.

You would think with as long as MRI tech has been around, someone would have come up with some DIY applications. I played around with those cards that allow you to see magnetic fields to some degree . Those are fun, particularly on inductors. I actually bought a phone with a FLIR built in because I was tired of burning my fingers looking for the short circuits. Imagine a single device that would allow you to see a huge swath (100μm-1nm) of the Spectrum compounded with magnetic resonance? If we could actually see the EM fields in a device as its working, we can diagnose faults and fatigue super fast. Couple that with ultrasonic hearing and you have the ultimate diagnostic device.

I will put those vibration Moters on my Cherae and connect then to my doorbell, when I listening to loud music on my headphones will give me feedback! oh, I don't have doorbell.

Blood oxygenation at 92% means you are have oxygen issues 😰 Less then 95% you have hipoxia. Those board or sensors are so far away to be accurate, do not use to track your health.

I've commented this on the hacksmith before but I'll say it again, the haptic motor Is perfect with a near distance sensor for alerting against creeps. Especially in the most precarious of event situations such as e3 or any other compact conventions

You mean the haptic feedback? Yeah, sounds like a fitting application.

Another great video. I don't agree with putting haptic devices in steering wheels. The first thing I do when I get a phone or play on a playstation is turn off the haptic feedback. I'm not sure what I hate about it but I certainly do not like it. If it was in my steering wheel it would drive me completely crazy!!!
