In-vitro validation of inertial-sensor-to-bone alignment

A major shortcoming in kinematic estimation using skin-attached inertial sensors is the alignment of sensor-embedded and segment-embedded coordinate systems. Only a correct alignment results in clinically relevant kinematics. Model-based inertial-sensor-to-bone alignment methods relate inertial sensor measurements with a model of the joint....

Inaccurate load compensation force during fast goal-directed elbow flexion

Wearable robotic lifting aids compensate a proportion of the gravity during heavy lifting and can thereby reduce the burden on the operator’s musculoskeletal system. This study investigates the effect of errors in the compensation force of an inaccurate load compensation system on fast reaching movements of an operator. In an experimental study,...

Non-invasive control interfaces for intention detection in active movement-assistive devices

Active movement-assistive devices aim to increase the quality of life for patients with neuromusculoskeletal disorders. This technology requires interaction between the user and the device through a control interface that detects the user’s movement intention. Researchers have explored a wide variety of invasive and non-invasive control...

Human movement characterization in indoor environment using GNU radio based radar

Human activity characterization based on gait signatures is important in several applications including medical, elderly care, police, biometric identification, etc. Cameras and on-body accelerometers are widely investigated for characterizing human activity. Nonetheless, in order to achieve wide acceptance, sensors to be used for these...
