Suitability of Liquid Crystal Polymer substrates for high frequency acoustic devices

Polymer substrates are widely seen as a low-cost route to flexible circuits for systems incorporating displays, sensing functions and transistors. To date most polymer-based devices have involved passive components such as humidity sensors, constructed using metals and additional organic layers. The starting point of the study described here, is whether more advanced components incorporating functional materials can be integrated into devices on polymer substrates. An understanding will be required of the material factors that limit performance and, if possible, techniques developed to circumvent them so that their performance can be compared to that of standard silicon-based components.
