Abstract

An integrated research and education CAREER program is proposed to build a foundation for achieving the PI's career goals: to transfer biology-inspired ideas into smart, small-scale sensors, and to educate future generations of students and researchers with multi-disciplinary perspectives. Inspired by the micro-scale ears of the fly Ormia, which show remarkable sound localization ability, the research plan is to develop a new class of miniature directional microphones. This entails a new approach for sensor development via the integration of biology-inspired solutions, mechanics modeling, micro-fabrication techniques, and optical detection strategies. The mechanics model will help unravel the underlying science of the fly's hearing mechanism and develop sensor design guidelines. The low coherence interferometer based optical system will overcome the limit of state-of-the-art detection techniques. This new bio-inspired sensing paradigm for sound localization is expected to have a significant impact in areas such as health care, safety, and defense. The learning experience of undergraduate and graduate students will be enriched through an inter-disciplinary curriculum. The interests of K-12 students in science and engineering will be stimulated by involving them in multi-disciplinary research activities at the University of Maryland. Participation of underrepresented groups will be broadened through educational activities and mentoring of the Women in Engineering program.
