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技术为糖尿病患者的定制鞋垫设计和制造有可能彻底改变提供给具有足球溃疡病史的糖尿病患者的护理质量，或者最好是对有溃疡风险的大量患者，但实际上没有溃疡。使用这种方法，矫形器的个性化可能会变得更加精确，一致且价格便宜，而不是利用仍然通常的手工制作。几家公司开发了能够自动生产此类矫形器的系统，在每种情况下；脚形的准确测量是系统的关键组成部分。现有方法使用复杂的脚数字化机器来测量脚的几何形状和CAD/CAM技术来创建鞋垫。这些系统非常昂贵，这笔成本的很大一部分是由于使用的脚数字化设备所致。该项目的目的是开发和原型一种廉价的设备，即触觉足迹，以测量三维形状 脚的足底表面并产生脚形的数字表示。拟议的设计的主要优势是其高分辨率，低成本和简单性，这使得谱专家和其他临床医生更容易获得。这项研究的初始阶段将开发功能原型设备和必要的软件。然后，第二阶段将完善此原型设计和随附的软件，降低其整体成本，并为市场介绍做准备。该项目是Diapedia的整体努力的一部分，以设计并为高危糖尿病患者提供矫形系统，该系统基于明确的科学支持的设计算法。
