Need help in debugging prototype device for ECG. It is based on a Texas instrument ADS11292 and is covering only two precordial leads V1 and V3. The problems we need to solve are: 1. Why ERA and ELA pads that are currently on PCB aren’t working properly? Signal is too noisy. Configuration is designed for connection with these sensor pads ([login to view URL]). How crucial are “snap connectors” for proper usage with above sensor pads, and how could that be implemented without additional parts? 2. How to implement dry electrodes that are integrated in PCB for proper reading of ECG signal. 3. Inspect wireless battery charger circuit and give solution how it should be implemented for best performance. 4. Is it possible that ground plane under the BL600 antenna is affecting the data wireless transmission heavily? 5. How to solve powering up and powering down a device? Placement and what kind of switch. Altium files are zipped.

Hi, from your schematic, I think the input singals of ERA and ELA need more filters and OPAMP, others need more inspections, thanks.

I have experience with Wireless Charging and PCB Design therefore I can quickly assess whether the existing product can be used, fixed or needs to be changed. I have implemented Wireless Charging on several products I have designed, meaning I can use exisiting schematics and layouts to ensure wireless charging will work for your product as well. I have dealt with noise issues in wireless communications before and am able to assess whether the antenna is causing issues. Thanks for your consideration! Cheers Tim
