MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Gourd‐Inspired Design of Unit Cell with Multiple Gradients for Physiological‐Range Pressure Sensing

Advanced Functional Materials, EarlyView.
Gourd‐shaped micro‐dome arrays with coordinated modulus, conductivity, and geometric gradients co‐optimize sensitivity and linearity in piezoresistive tactile sensors. Under pressure, a solid upper dome embeds into a porous lower dome, triggering rapid contact‐area growth and series‐to‐parallel conduction, enabling unsaturated, intensity‐resolved ...

Reliability of hemodynamic parameters measured by bioimpedance cardiography at different intensities during incremental exercise testing

Frontiers in Cardiovascular Medicine
BackgroundBioimpedance cardiography offers a non-invasive and time-efficient method to measure hemodynamic parameters. Previous studies only investigated its reliability under steady-state conditions and at maximum load but not at ventilatory thresholds (

THE STROKE VOLUME IN JUVENILE BORDERLINE HYPERTENSION

Japanese Circulation Journal, 1975
Hemodynamic changes in supine and upright position and during exercise were studied in 144 men including 37 normal subjects and 107 patients with borderline hypertension. Borderline hypertensives were classified in 4 groups, according to the basal level of heart rate and stroke index. In the first two groups, stroke index was normal, but heart rate was
