Wearable hip protectors represent a promising strategy for preventing fall-related hip fractures in high-risk older adults. However, research reveals conflicting evidence on their effectiveness, due in part to poor user compliance in wearing the device. This thesis investigates the effect of pad geometry and material properties on both the biomechanical effectiveness and user preferences in product selection. Pad geometry and material properties were found to significantly influence the biomechanical effectiveness of hip protectors. Pads of high thickness, moderate hardness and large surface area provided highest levels of force attenuation (max = 46%). Hip protectors with high level of perceived comfort and protective value achieved the greatest success for overall user acceptance. Participant preferences changed substantially after education on biomechanical performance, shifting to pads of higher thickness and hardness. The optimal pad design was found to possess a thickness of 35mm, hardness of 43 durometer, and surface area of 365 cm².
