Explaining that they were interested in how metabolic energy is

Cheap Wearable Electric Nanogenerator Harvests

2020-11-3  We once placed our nanogenerator on a person’s arm, and a swinging arm’s airflow was enough to generate power. The device is a nanogenerator (not a turbine) made of two plastic strips housed in a tube that flutter (clap together) when there is airflow. It gathers energy through the triboelectric effect the same phenomenon that generates

Understanding how an arm swing enhances

The effect of arm swings on vertical jumping

2001-5-16  4: The arm swing contribution to the hip joint torque may be divided into two components, i.e., shoulder joint torque applied to the trunk (Ts) and the torque created about the CG of the trunk by the shoulderjoint force applied to the trunk (Tf) (Fig. 4).The peak of the arm swing contribution (the sum of Ts and Tf) occurred at about the middle of the propulsive phase, which is considered to

The swinging lever-arm hypothesis of muscle

1997-2-1  However, there were indeed problems with this hypothesis — the swinging cross-bridge needed an update. In fact, the hypothesis was never very clear about how the cross-bridge moved on actin, and has been discretely modified over the years into a swinging lever-arm hypothesis, in which the bulk of the cross-bridge is envisaged to bind to actin with a more or less fixed geometry, and only the
