Abstract: The sweet spot on a cricket bat is defined as the point where the ball receives maximum acceleration. Sweet spot impacts are accompanied by minimal jarring of the hands and forearms. Using 3 axis accelerometers mounted on the bat and the wrists, ball strikes were recorded for defensive drives along the ground. There is significant evidence that sweet spot hits have low levels of vibration in the wrist sensors so that small, battery powered, accelerometers can be used to discriminate sweet spot hits during normal match play and practice.
