[Kudly]Hug sensor

Hello everybody,


This afternoon, we decided with the team to add a new feature on our bear. A hug sensor measuring how the child loves his Kudly, or how strong he can strike it. But there is a problem, we don’t know how to implement it and which sensor to use. We found this kind of sensor http://fr.farnell.com/bei-sensors/9610r3-4kl2-0/capteur-position-lineaire-26-9mm/dp/1607968 that we can put in our bear but that implies to create skeleton all around our bear and we are afraid to stiffen it too much. Does anyone have an other idea who would be better ? Thank you for the feedback.
