Best Force Sensor or Strain Gauge for Biomechanical Application?

Dylan A last edited by

Hi all, I am looking for suggestions on the best strain gauge or other force sensor to be used in measuring the reaction force between the hand and the wheelchair wheel during wheelchair propulsion. The force Ft which is th reaction force needs to be meaured.

My design includes strain gauges between the pushrim and wheel as seen circled in the picture attached. I need to measure the reaction force so the output will be one vector of voltage. The voltage is a meaure of the force. Anyone have any specific strain gauge suggestions? All help is useful!

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Thanks for the offer @TheoL ! I have moved on to a differenct project. Also, a lesson that I have learned many times, "If it works, don't fix it!" -OSD

LiFePO4 batteries are a great choice because they have a long life cycle and are much safer than other lithium-based batteries. However, you need a solar charge controller that’s compatible with LiFePO4 to prevent overcharging and maintain efficiency. A good MPPT controller can significantly boost energy harvest from your panels. Also, ensure your solar panel output matches your power needs. If you're in solar ireland, you might find some local companies that offer tailored solutions for maximizing solar efficiency in lower light conditions.

hey @dirkc, maybe you can trigger your interrupt to rising and falling edge and use millis() to see how long the press was?

@OldSurferDude My old 2.0 setup is with nRF24L01 radios. This is a link to the thread on some light switches that I designed and built. https://forum.mysensors.org/topic/7376/us-decora-wall-switch-continued/2 I am aware that you cannot have two MQTT gatways. When I designed my old setup I was not that familiar with MQTT so I never ended up implementing it. On the home assistant server that I have set up though, I have installed the MQTT broker on there so I should be able to comunicate with any MySensors stuff over MQTT in the future devices I make/set up. As I mentioned, I do have a Home Assistant box that I have started about 4 months ago and eventually want to migrate my Vera equipment to the HA box. As for the YAML and Python, I'll muddle my way through. used to program in PHP and have done enough on Arduino that I'm sure it won't hurt my brain too much.
