The aim of this project is to expand our means of interacting with electronic devices by creating three technologies: (1) transparent and stretchable touch-sensitive films that generate an electrical signal due to ion motion, (2) stretchable and transparent capacitive proximity sensors and (3) thin, bendable tactile feedback displays that are intended to provide localized vibration or textural feedback. These interfaces will be thin films, soft, flexible and conformable to virtually any surface. The university team are combining their expertise in polymer artificial muscle, rapid prototyping/alternative micro-fabrication, low-power electronics, signal processing and haptics with the low power electronics, mobile device and medical device know-how of the partner to create new approaches and possibilities in human-device interaction. On the sensing side we explore two new approaches both using soft but tough gel films as ionically conductive layers that are also stretchable and highly transparent. Tactile interfaces employ conducting polymer trilayer technology that is intended to enable perceptible displacements and forces to be generated. Advances in conducting polymer actuators over the past ten years have substantially improved performance, while modeling has enabled simulation and improved control. Thus we believe these actuators are ready for use in devices that can take advantage of their low voltage and high work to volume.

这个项目的目的是通过创造三种技术来扩展我们与电子设备交互的手段：(1)透明和可拉伸的触摸敏感薄膜，由于离子运动产生电信号，(2)可拉伸和透明的电容接近传感器和(3)薄的，可弯曲的触觉反馈显示器，旨在提供局部振动或纹理反馈。这些界面将是薄膜，柔软，灵活和适应几乎任何表面。大学团队正在将他们在聚合物人造肌肉、快速原型/替代微制造、低功耗电子、信号处理和触觉方面的专业知识与合作伙伴的低功耗电子、移动设备和医疗设备专业知识相结合，以创造人机交互的新方法和可能性。在传感方面，我们探索了两种新方法，它们都使用柔软但坚韧的凝胶膜作为离子导电层，这种膜也可拉伸且高度透明。触觉界面采用导电聚合物三层技术，旨在实现可感知的位移和力的产生。在过去的十年中，导电聚合物致动器的进步大大提高了性能，而建模使仿真和改进控制成为可能。因此，我们相信这些致动器已经准备好用于可以利用其低电压和高功的设备。
