Review of Piezoelectric Properties and Power Output of PVDF and Copolymer-Based Piezoelectric Nanogenerators [PDF]
The highest energy conversion efficiencies are typically shown by lead-containing piezoelectric materials, but the harmful environmental impacts of lead and its toxicity limit future use.

Effect of Power Output and Pedaling Cadence on Plantar Pressures in Professional Cyclists with Overuse Injuries [PDF]
Background: Plantar pressure analysis provides insight into load distribution at the foot–pedal interface during cycling; however, its modulation by pedaling power, cadence, and overuse injury status remains poorly understood by professional cyclists. It

Acute Effects of Forefoot Wedges on Concentric Power Output During Loaded Back Squats in Elite Female Handball Players: A Randomized Crossover Study [PDF]
The foot’s windlass mechanism (WM), engaged by hallux dorsiflexion, is a key determinant of lower-limb propulsive efficiency in explosive sports. This randomized within-subjects crossover study examined whether forefoot wedges of varying angulation ...
