The broader impact/commercial potential of this project begins first are foremost with integration of these 3-d interactive displays with mass produced electronic devices. From the small scale (watches, smartphones) to the large scale (collaborative workplace displays), adding pressure and temperature sensitivity could introduce a whole new level of input and functionality. In addition to improving functionality and productivity, these displays could widen the capabilities of gesture-based input for the elderly and disabled. The multi-touch display market exceeds $10 billion and continues to grow, indicating a massive commercial opportunity. However, combined pressure- and temperature-sensitive films can have broader applications beyond displays. A natural extension for these sensors is wearable devices, especially those aimed at preventative and diagnostic healthcare (e.g. monitoring blood pressure, core temperature, wound healing). Another logical application is robotics, where combined pressure and temperature sensor arrays can function as ?electronic skin?, mimicking the pressure and temperature sensitivity of human skin. Finally, since this class of sensors is compatible with large-scale semiconductor manufacturing processes, they are expected to be low in cost, which would enable a future in which walls, windows, floors, and other surfaces can be infused with pressure and temperature sensitivity, adding significantly to the Internet of Things.This Small Business Innovation Research (SBIR) Phase I project is focused on developing multi-touch displays that are responsive to both pressure and temperature, in order to create a truly 3-dimensional interactive display experience. A handful of commercial touch displays already offer pressure sensitivity, which extends user input ?into the screen?, but including sensitivity to temperature could allow user input ?above the screen? as well. It may now be possible to introduce both temperature and pressure sensitivity to displays by using a new class of transparent, polymer-based, thin-film pressure and temperature sensor arrays. These sensor arrays utilize finely-tuned transparent polymers that are highly sensitive to either pressure or temperature. The goal of this research is to develop a single transparent film with both pressure and temperature sensitivity, and to integrate this film beneath the glass of a display. This will first require combining the pressure- and temperature-sensitive films without deteriorating the sensitivity of either one, by experimenting with lamination and deposition techniques. Another key activity will be to improve the transparency of the temperature-sensitive film by adjusting its material composition. Finally, the sensitivity of this film under a glass cover will need to be evaluated through extensive input testing.

这个项目的更广泛的影响/商业潜力首先开始于这些3-d交互式显示器与大规模生产的电子设备的集成。 从小尺寸（手表、智能手机）到大尺寸（协作工作场所显示器），增加压力和温度灵敏度可以将输入和功能提升到一个全新的水平。 除了提高功能和生产力之外，这些显示器还可以拓宽老年人和残疾人基于手势输入的功能。 多点触控显示器市场超过100亿美元，并继续增长，这表明了巨大的商业机会。 然而，组合的压力和温度敏感膜可以具有显示器之外的更广泛的应用。 这些传感器的自然延伸是可穿戴设备，特别是那些旨在预防和诊断医疗保健（例如监测血压，核心温度，伤口愈合）的设备。 另一个合乎逻辑的应用是机器人，其中组合的压力和温度传感器阵列可以作为？电子皮肤模仿人类皮肤的压力和温度敏感性。 最后，由于这类传感器与大规模半导体制造工艺兼容，因此预计它们的成本较低，这将使未来的墙壁，窗户，地板和其他表面可以注入压力和温度敏感性，大大增加了物联网。这个小企业创新研究（SBIR）第一阶段项目的重点是开发多，触摸显示器对压力和温度都有响应，以创建真正的三维交互式显示体验。 一些商业触摸显示器已经提供了压力敏感性，这扩展了用户输入？在屏幕上？但是包括对温度的敏感性可以允许用户输入？在屏幕上方？也现在，通过使用一类新的透明的、基于聚合物的薄膜压力和温度传感器阵列，可以将温度和压力敏感性引入显示器。 这些传感器阵列利用对压力或温度高度敏感的微调透明聚合物。 这项研究的目标是开发一种具有压力和温度敏感性的单一透明薄膜，并将这种薄膜集成到显示器的玻璃下面。 这将首先需要结合压力和温度敏感的薄膜，而不恶化任何一个的敏感性，通过实验层压和沉积技术。 另一项关键活动将是通过调整材料成分来提高温度敏感薄膜的透明度。 最后，这种胶片在玻璃盖下的灵敏度需要通过广泛的输入测试进行评估。
