Hi,

I'm trying to measure a presure of grasping with Wii fit board's sensors,

which has four straingages at it's corners.

I'v got these sensors(attached picture), but I don't know how to get spatio-tempral data from here.

My questions are below;

・Unfortunately, my main PC(Lenovo, Ideapad520,Windows10) cannot connect these sensors through bluetooth, is there any dongles to connect? What is the profile and class for Wii fit board?

・What is an appropriate software to get spatio-temporal data? It's desiable for free and working on Windows.(I'v already tested " Posturography test"( http://www.nrhb.webs.upv.es/resources/ ), but it didn't work)

・ How to set the four sensors to measure finger preassure on a convex surface?

I really appreciate any advises and suggestions, I'm not familiar with a sensor and basic Physics.

Thank you.

Takahiro
