The development of wearable sensor for arcus pedis pressure assessment

This paper demonstrates the development of an insole-based wearable sensor embedded in footwear for the arcus pedis or foot plantar pressure assessment. The information data results of the foot landing patterns obtained from such foot plantar pressure assessments are significant in posture research. Postural injuries to the lower limbs may occur to most people due to unsuitable footwear selection and unrecognized foot plantar conditions. Several assessments have been conducted to examine the different types of the foot plantar arch. 20 participants with various arches types or chipped arcus pedis were involved in this examination. Participants are required to run on a treadmill at three different speeds to examine the plantar pressure distribution. There are two FSR sensors used, each on the plantar surface of the forefoot and rear foot. This paper concludes that different arcus pedis types such as low arch, medium arch and high arch are associated with the various pressure distributions under the foot. Wearable sensors that refer to biological sensor devices have the potential of clinical care to assess the state of foot plantar pressure and injury prevention methods.
