Commerical (cheap) wearable sensor for joint/segment angles

[Bernard]

Hi Biomch-L users,

I wondered if there is a cheap commercial wearable sensor that can collect free-living joint/segment angles in addition to the typical accelerometry data. Something like an Actigraph for angles. I do not want the high-end equipments (e.g. Xsens or Noraxon) as I hope to collect say 24 hour free-living knee kinematics en-masse.

Thank you everyone,

Regards,
Bernard

Hi,

I am fairly confident that deriving joint angles using wearables is still an open problem. I don't think you will find commercially available equipments to do that (apart as you stated Xsens and similar) in a persistent monitoring fashion, if you do, be suspicious haha.

Perhaps a portable data logger and goniometer setup?

I think that IDEEA could be a good solution for you.

Other option is programming some IMUs units. A cheap programmable IMU sensors:

Hi,

I have used this in the past.

It's decent for its price, but I can't guarantee its output will be what you need.
Take a look at it though, it works out-of-the-box.

Cheers
