One important health problem that could affect diabetics is diabetic foot syndrome, as risk of ulceration, neuropathy, ischemia and infection. Unnoticed minor injuries, subsequent infection and ulceration may end in a foot amputation. Preliminary studies have shown a relationship between increased skin temperature and asymmetries between the same regions of both feet. In the preulceration phase, to develop a smart device able to control the temperature of these types of patients to avoid this risk might be very useful. A statistical analysis has been carried out with a sample of foot temperature data obtained from 93 individuals, of whom 44 are diabetics and 49 nondiabetics and among them 43% are men and 57% are women. Data obtained with a thermographic camera has been successful in providing a set of regions of interest, where the temperature could influence the individual, and the behavior of several variables that could affect these subjects provides a mathematical model. Finally, an in-depth analysis of existing sensors situated in those positions, namely, heel, medial midfoot, first metatarsal head, fifth metatarsal head, and first toe has allowed for the development of a smart sock to store temperatures obtained every few minutes in a mobile device.
一个可能影响糖尿病患者的重要健康问题是糖尿病足综合征，其风险包括溃疡、神经病变、缺血和感染。未被注意到的轻微损伤、随后的感染和溃疡可能导致足部截肢。初步研究表明，皮肤温度升高与双脚同一区域的不对称之间存在关系。在溃疡前期，开发一种能够控制这些类型患者体温的智能设备以避免这种风险可能非常有用。对从 93 个人获得的足部温度数据进行了统计分析，其中 44 人患有糖尿病，49 人没有糖尿病，其中 43%是男性，57%是女性。热成像相机获得的数据成功地提供了一组感兴趣的区域，在这些区域中，温度可能会影响个体，并且影响这些对象的几个变量的行为提供了一个数学模型。最后，对位于脚跟、中足内侧、第一跖骨头、第五跖骨头和第一脚趾的现有传感器进行了深入分析，这使得能够开发出一种智能袜子，以便在移动设备中每隔几分钟存储一次获得的温度。
