Wearable gait retraining could enable benefits from laboratory retraining systems to extend to a broad portion of the population, which doesn’t live near or have access to laboratory gait retraining testing facilities. While few portable gait retraining systems utilize both wearable sensing and wearable feedback, several systems employ critical components. The purpose of this paper is to provid...

In this research we introduce a wearable sensory system for motion intention estimation and control of exoskeleton robot. The system comprises wearable inertial motion sensors and shoe-embedded force sensors. The system utilizes an instrumented cane as a part of the interface between the user and the robot. The cane reflects the motion of upper limbs, and is used in terms of human inter-limb sy...

Wearable computers intelligently combine data from motion sensors placed at various locations on body with the aim to recognize human activities for the applications of healthcare and wellness. Many activity recognition algorithms for wearable computers exist today. To ensure the effectiveness of the recognition algorithms, the sensors typically have to be worn with a known orientation, since p...

Piezoelectricity provides an ideal electromechanical mechanism with emerging applications in wearable devices due to its simplicity and self-powered nature. However, the 3D printing of piezoelectric still faces many challenges, including material printability, high energy poling process, low dimensional accuracy. This study demonstrates, for first time, a tellurium nanowire-based device fabrica...

Biomechanical energy harvesting is a feasible solution for powering wearable sensors by directly driving electronics or acting as wearable self-powered sensors. A wearable insole that not only can harvest energy from foot pressure during walking but also can serve as a self-powered human motion recognition sensor is reported. The insole is designed as a sandwich structure consisting of two wavy...
