https://devzone.nordicsemi.com/f/nordic-q-a/109850/chip-card-for-cpr-useHello, I am writing on behalf of a group of students from NTNU who are working on the development of a new health technology product and are wondering if we could get some help regarding chip technology. We want the product to be a chip-like deviceen-USTelligent Community 13Wed, 03 Apr 2024 13:59:13 GMThttps://devzone.nordicsemi.com/thread/476923?ContentTypeID=1Wed, 03 Apr 2024 13:59:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0c3b0d5c-19c6-49de-b6d3-1ff2491c16ffEdvin<p>Hello,</p> <p>Sounds interesting. From a Bluetooth perspective, this is a quite simple application, which you could probably run on any of the nRF52 series chips. What you need to figure out is what other sensors you would need to measure the compression rate and depth. I am not sure what exactly would be the best sensor for this. Accellerometer? Perhaps a flex sensor or something?</p> <p>Then you can do the counting and timing on the nRF, and send it over BLE. When you get there, I can help you if you are stuck, but what you need to figure out is what sensors you want to use. Try to get hold of some breakout boards with the sensors you want to use, and you can connect them to our Development kits to get started with the code before you do your own PCB design.</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
