Purpose: Design a schematic for a wearable ECG signal monitoring device that is compact and sends readings via Bluetooth.

Components:

Arduino Nicla Sense ME: To serve as the central processing unit of the device. MCP3911: To capture the ECG signal. AD8606: To amplify the ECG signal. Battery: To power the device with a consideration for the battery to be rechargeable via a Type-C port. Specifications:

The device must be small and wearable, like the one shown in the image provided. It should have Bluetooth capabilities for transmitting data. Include a charging circuit for the battery using a Type-C connection. Enhancements:

Suggest potential improvements in design for efficiency, size reduction, or additional features. Constraints:

The size and shape should be as unobtrusive as possible for ease of wear. Note: Please advise on the inclusion of any additional components that may be necessary for the operation, stabilization, or improvement of signal quality.
