Abstract Summary
In this paper, we present a novel smart wearable and wireless body-fixed inertial sensor (i-Sens) based design for estimation of joint kinematics in the sagittal plane. Preliminary testing has been done on normal volunteers with this bodyworn i-Sens sensors kept at knee and hip level on one side. The performance was compared for both indoor and outdoor environmental conditions. The accuracy of the joint angle estimated for a single stride was within the normal walking range suggesting that the i-Sens can be considered as an alternative method for kinematic analysis.
