Introduction

Diabetes mellitus (DM), is a kind of worldwide chronic disease: it is estimated that 8.3% of the global adult population has diabetes in 2015. More specifically, the percentage in the United States is 9.4% [1][2]. In the United States, diabetes cost US$245 billion in 2012 [3]. The related economic cost of diabetes complications was estimated to be US$612 billion in 2014 [4].

Diabetes foot ulcer (DFU) is a major and harmful complication of diabetes [5]. As a metabolic disorder as shown in Figure 1, diabetes can disturb the innate wound healing mechanism, prolong the formation of mature granulation tissue and reduce its tensile strength [6]. Since the pressure of the whole body is on the feet, feet are one of the most vulnerable parts of the body of people with diabetes. As shown in Figure 1 below, a foot ulcer resulted from diabetes is more likely to happen due to pressure from ground, shoes and nearby toes. Diabetes foot ulcer has led to 84% of all diabetes-related lower-leg amputations [7]. Without effective treatment, DFU has severe consequences.

Based on the technique of fiber detection, SenseMove aims to become a possible solution to the monitoring of plantar pressure (the pressure on the foot skin) dynamically with an optic fibre in-sole (OFI) with related posture camera and data analysis software. It combines the advantages of non-bare foot measurement with low-cost design. This system could assist in the prevention and treatment of DFU like making customized shoes and improve the quality of patients’ life.
