The energy available per event scales with the mechanical impulse or strain energy imparted to the transducer (e.g., impact energy mv for an ice particle), and peak electrical output depends on modal coupling (placing the piezo element at high-strain locations), electromechanical coupling coefficients, and the dynamic bandwidth (resonant amplification improves yield if impact or shedding excites modal frequencies)

This ones highly personal, but I prefer a sleeker fit and some nice choices in colours to the typical boxy design that most men seem to favour

Barely move it
