The Bio Highway – Wearable Design Test Results

Testing

 

I' was working on testing of my wearable design and in the process of testing I've broke my key component in the project - the heartbeat sensor. One of the LED legs lost contact,

 

Recovery Attempt

 

I've tried to solder the led leg back, but I was not able to fix it.

Logistics Challenge

 

This sensor was sourced from China. I have still an outstanding order from the beginning of February for a similar sensor. it was no possible for me to get a replacement part in time to finish this challenge.

 

New Hopes

 

As challenge was extended I've try to come up with an alternative design. I have several green LEDs and photo resistors.So I put together for a quick test.

But the resulting signal contained to much noise, so I was not able to detect any heartbeat from its signal.

And this is what I was getting with the real heartbeat sensor while it was working.,

So the alternative design is too simplistic and is not a viable option.

 

Summary

Some lessons learned from it:

  • The mechanical side of wearable design is very important. It should withstand wear and tear.
  • There is no simple replacements for a quality sensor.
