Presidential Young Investigator Award (Supplemental Funding for Women Engineering Research Assistants)

这是总统青年调查员奖。 的主题 本研究系研制一种基于 聚酰亚胺（PI）的介电常数特性。 强调 这种传感器的发展将取决于可靠性和寿命， 特别是在恶劣的环境中。 经验证据表明， 水在PI表面上的长时间冷凝导致器械 失败 这项研究将试图描述预期的变化 在表面化学中可能导致可靠性和老化问题。 此外，PI的机械性能将被表征， 特别是热膨胀系数和膨胀， 湿度，目的是指定应力降低的结构 水平和更高的可靠性。

This is a Presidential Young Investigator award. The subject of this research is the development of a relative humidity sensor based on the permittivity properties of polyimide (PI). Emphasis on the development of this sensor will be on reliability and lifetime, particularly in hostile environments. Empirical evidence indicates that prolonged condensation of water on the PI surface leads to device failure. This research will seek to characterize the expected changes in surface chemistry that may lead to reliability and aging problems. Also, the mechanical properties of PI will be characterized, particularly the thermal coefficient of expansion and swelling due to moisture, with the aim of specifying structures with reduced stress levels and greater reliability.
