Crack Monitoring in Rotating Shaft Using Rotational Speed Sensor-Based Torsional Stiffness Estimation with Adaptive Extended Kalman Filters [PDF]
Sensors, 2023 In this study, we present an alternative solution for detecting crack damages in rotating shafts under torque fluctuation by directly estimating the reduction in torsional shaft stiffness using the adaptive extended Kalman filter (AEKF) algorithm.

Evaluating the cutaneous involvement in scleroderma: torsional stiffness revisited [PDF]
Rheumatology, 2001 The pace, progression and extent of the skin lesions in scleroderma may parallel the risk of new internal organ involvement and the progression of existing internal lesions. Accurate assessment of cutaneous change permits an evaluation of patient prognosis and the response to therapy.

3D Printed Meter-Scale Soft Origami Robots Capable of Load-Bearing Actuation Via Crease Stiffness Modulation. [PDF]
Adv Sci (Weinh)Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.
