You posted in the Sensors forum. Here I would expect to see a schematic diagram of your sensor. I would expect you to publish your code. I would expect a detailed explanation of how you solved the problem of movement related noise on the output of your sensor. How you used a clever combination of software and electronic circuit design to ignore the effects of running or jumping up and down and output a signal proportional only to heartbeat.
There is a forum for new product releases, where people expect to see meaningless marketing buzzwords and this isn't it.
