I have made a belt for sensing when our unborn child kicks from the inside. This is useful for tracking activity and health of the baby. In my current configuration, I am using a piezoelctric sensor strip but there are a few issues.
- The strip is small and cannot cover a large surface area.
- It will not discriminate between kicks and movement caused by the mother herself.
I was able to condition the signals and send them over BTLE but the sensor is an issue.
Can anyone suggest? Thanks.
