DESCRIPTION (provided by applicant): The design and manufacture of custom insoles for patients with diabetes using CAD/CAM technology has the potential to revolutionize the quality of care provided to diabetic patients with a history of foot ulceration, or preferably to the much larger group of patients at risk for ulceration, but who have not actually ulcerated. Using this approach individualization of the orthotic could become much more precise, consistent and less expensive than utilizing the still usual handcrafting. Several companies have developed systems that enable the automated production of such orthoses and, in each case; the accurate measurement of foot shape is a critical component of the system. Existing approaches use sophisticated foot digitizing machines to measure foot geometry and CAD/CAM technology to create the insole. These systems are very costly, and a significant portion of this cost is due to the foot digitizing devices used. The objective of this project is to develop and prototype an inexpensive device, the Haptic Footprint, to measure the three-dimensional shape of the plantar surface of the foot and generate a digital representation of the foot shape. The major strengths of the proposed design are its high resolution, low cost, and simplicity, which make it much more accessible to pedorthists and other clinicians. The initial phase of this study will develop a functional prototype device and necessary software. The second phase will then refine this prototype design and accompanying software, reduce its overall cost, and prepare it for market introduction. This project is part of an overall effort at DIApedia to design and offer an orthotic system for at-risk diabetic patients that is based on clear scientifically supported design algorithms.

描述（由申请人提供）：使用CAD/CAM技术为糖尿病患者设计和制造定制鞋垫，有可能彻底改变为有足部溃疡病史的糖尿病患者提供的护理质量，或者更好地为更大的有溃疡风险但实际上没有溃疡的患者群体提供护理质量。使用这种方法个性化的矫正可以变得更加精确，一致性和更便宜，比利用仍然常见的手工制作。几家公司已经开发出能够自动生产这种矫形器的系统，并且在每种情况下，脚形的准确测量是系统的关键组成部分。现有的方法使用复杂的足部数字化机器来测量足部几何形状，并使用CAD/CAM技术来制造鞋内底。这些系统非常昂贵，并且该成本的很大一部分是由于所使用的脚数字化设备。这个项目的目标是开发一种廉价的设备，触觉足迹，测量三维形状的原型。 足部的足底表面，并生成足部形状的数字表示。所提出的设计的主要优点是其高分辨率，低成本和简单性，这使得它更容易获得儿科医生和其他临床医生。这项研究的初始阶段将开发一个功能原型装置和必要的软件。第二阶段将完善原型设计和配套软件，降低总体成本，并为市场推出做好准备。该项目是DIApedia整体努力的一部分，旨在为有风险的糖尿病患者设计和提供一种基于明确的科学支持的设计算法的矫正系统。
