A Tekscan F-Scan 9811 force sensor was attached to the grip of a standard driver (graphite shaft, titanium head, 9.5 loft) as shown in Fig. l. The 9811 is a thin-film, flexible force sensor that utilizes a semi-conductive ink applied between electrical contacts and thin polyester sheets. Application of force to the sensor decreases its resistance, and through calibration the magnitude of force to the force can be determined from the voltage output. It is capacle of measuring up to 517 kPa (75 psi), across a 6 by 16 matrix of sensing cell (Known as sensels), i.e. 96 sensing elements in total.
