 It is now time for our favorite segment. It's brought to you by digikey and ate a fruit It is time for That's right ion MPI that's right with a great new theme song now Okay, is an MPI this week this week's iron MPI is the max 86 150 combined pulse oximetry and EKG Sensor chip medical chips in the news from max medical chips in our new product introduction Right Well, we did a pulse oximeter tear down as one of a video a couple weeks ago and people in the chat were saying well How can I make my own pulse pulse oximeter and they're like oh, there's this maximum chip So I kind of looked into like you know what what's up and this is actually a more recent upgrade to the maximum pulse oximetry chips the 86 86 150 what I think is interesting about it is it adds an EKG And long front end to it So it's not only for blood gas, but also you can actually get like a pretty good EKG signal I was actually trying out this test kit So let's go to the overhead Yeah, I want to show a few things with this collection here Yeah, this is the depth and we have you know what you wanted to show and you actually have one here Yeah, I didn't know if I was gonna get it in time, but I did so here's the chip itself Maybe I'll zoom in super close because I want to show that I'll just focus in on it. Yeah, you can Okay, so the other thing we can do tell me when it's where you want it There you go, okay. Yeah So let's see if I can oh my god, you're so close Yeah, so you can see that this is actually there's a chip inside and you can see the two LEDs over here It's pretty good. Yeah, this is pretty amazing and then As soon as I say it's pretty good. It's too much. Yeah, it's too much We saw there. There's there's some LEDs Oh Wow, it's totally It's totally unhappy. This is so does not like it. Hold on. We went we went too much. We went too far Can you zoom out? Okay Sorry exciting times here at the overhead camera So we've got a maximum feather here, so that's kind of cool We didn't pick this because it uses a feather and is basically a feather wing, but that's a nice bonus This is a maximum cortex m4 chip and it's got a little Bluetooth module as well And then here is you know that the pulse oximetry chip so to do the pulse oximetry You put your finger over this and you don't have to have like LED and sensor on two different sides It actually bounces the light through the finger and then detects it on the same die Which is kind of nice because it's a simpler build also means it can go into wearables a lot easier It can go to like a wrist watch or something that goes on on your ears For example your fingertip, but it's an easier construction because you don't have to worry about light shining through the finger You just need You know it to be close to the skin and here's what's interesting. So these are two dry contacts For EKG or ECG measurements, so normally you have EKG where you have you know probe contacts go to You know left right and leg Or maybe just left right if it's a very simple one For this one you actually just put your thumbs on it and it actually can measure Your EKG through that like if you have seen gym equipment where you grab it with your fingers or you have a little Handheld EKG. Yeah, it's the same kind of technology there It's actually it's a good enough analog front end. I tried it out and you can really get EKG signal out of it Another thing that's really nice about this. Let's go to the photos. Yeah, you have a few we've got these Yeah, so here's showing how you can you know you put two fingers on and then a third finger on top to do the pulse oximetry So it's a kind of a nice combo. You see there's almost no components needed There's only like a couple capacitors and resistors Required it's a very integrated chip, which I think is nifty I even show like they're like here's all you need to hook it up. It has I squared T out with an interrupt pan So I think it's 1.8 volts You'll need a level shifter but other than that you can use it with like pretty much any microcontroller you like and You get some really good bio data. I'm gonna definitely make a breakout with this Maybe even like a feather wing because this is a cool chip and I think people Will definitely use this for projects. I'm also wondering if maybe the ECG can be used for muscle detection It's while not just Heart rate so like you can tweak all the filters and the gain and stuff I want to see what you can do. What's cool is like, you know, this is our this is a feather format Yeah doing this ion MPI thing with digikey and it happens to be a very useful thing that you're here about in the news Right now. Yeah, so this is a good ion MPI this weekly data So if folks want to get it, they should go to digikey.com and they should look for this part number That's right. That's the part number for the individual chip. It comes in tray and also Tape in real. I've got a little piece of tape here. I got 10 10 sensor so you get it on tape Yes, I can show you the underside is you know a little bit complicated, but not too bad is definitely pickin placeable We flowable So integrated it's not too inexpensive either. It's only a couple bucks It's a great way to make a bio Feedback or bio reading sensor circuit and then the eval kits very affordable to you I said just picking it up because it has this nice bluetooth connectivity software So I got it running on my windows machine in like 10 minutes It was super easy and we'll do a little write up about it and you can you know It starts graphing the data, you know within a couple minutes of of you downloading it and installing it So a very easy sensor kit nice work maxim and that is ion MPI this week brought to you by digikey and
