Tactile stimulators are used as a research tool in tactile psychophysics and cutaneous pattern perception, neuro- physiological studies of tactile sensitivities, as a diagnostic tool for evaluation of changes in tactile sensitivity associated with disease and trauma, as a novel man-machine interface, and as prosthetic aids for the blind and deaf. The primary objective of this Phase II SBIR contract is the development and fabrication of a standardized, modular, general purpose, versatile Multipoint Tactile Array (MTAC) System, capable of controlling many types of tactile arrays. The MTAC design objective is to control 4 modular arrays, with each array containing 256 points. The secondary objective is to overcome the limitations of the present state of the art of tactile arrays with regard to density, number of stimulators, bandwidth, and the predictability of skin deflection. In this regard, the design objective is to produce an ultra-dense array with deflection of 30 microns, and a bandwidth in excess of 0-400Hz.

触觉刺激器被用作触觉的研究工具 心理物理学和皮肤图案知觉，神经- 作为诊断工具的触觉敏感性的生理学研究 用于评估与以下相关的触觉敏感度的变化 疾病和创伤，作为一种新颖的人机界面，以及作为 盲人和聋人的假肢辅助器。 这份第二阶段SBIR合同的主要目标是 一种标准化、模块化、通用化的开发与制造 用途：多功能多点触觉阵列(MTAC)系统， 能够控制多种类型的触觉阵列。MTAC 设计目标是控制4个模块化阵列，每个阵列 包含256个点。 第二个目标是克服 关于密度的触觉阵列的技术现状， 刺激物的数量、带宽和皮肤的可预测性 偏转。在这方面，设计目标是产生一个 偏转30微米、带宽的超高密度阵列 超过0-400赫兹。
