已经开发了一个用于设计和分析座椅支撑和座椅组织界面的系统。它具有控制座椅表面形状的能力，同时测量表面施加到臀部的压力。使用安装在每个支撑元件顶部的旋转头中的硅压力传感器在11 × 12矩形阵列的支撑元件上测量压力。表面形状的控制通过支撑元件沿其各自的垂直轴沿着的选择性线性平移来调节。该系统的闭环控制允许基于可编程标准的支撑表面的动态配方。该系统预期用作研究工具，以便于研究支撑表面形状与界面压力之间的关系，以及支撑表面形状与软组织变形之间的关系。本文的目的是介绍系统仪表及其设计和开发背后的基本原理。本文还介绍了几个测试的结果，以评估系统的精度和性能。这项评估包括对10名身体健全的受试者进行试点研究。这些系统评估的结果表明，该系统是能够进行重复和精确的测量的压力和表面元素的位置，并可以制定支持表面形状，满足指定的优化标准。
A system for the design and analysis of seat support and buttock tissue interfaces has been developed. It has the ability to control the seating surface shape while measuring the pressure applied to the buttocks by the surface. Pressures are measured over an 11 x 12 rectangular array of support elements using silicon pressure sensors mounted in a swiveling head atop each support element. Control of surface shape is mediated by selective linear translation of the support elements along their respective vertical axes. Closed-loop control of the system allows for the dynamic formulation of a support surface on the basis of programmable criteria. The system is intended to function as a research tool to facilitate the study of the relationships between support surface shape and interface pressure, and support surface shape and soft tissue distortion. The purpose of this paper is to present the system instrumentation and the rationale behind its design and development. The paper also presents the results of several tests to evaluate the accuracy and performance of the system. This evaluation included a pilot study on 10 able-bodied subjects. The results of these system evaluations indicate that the system is capable of making repeatable and precise measurements of pressure and surface element position and can formulate support surface shapes that satisfy specified optimization criteria.
