Hello there! As a current junior undergrad, it is time to start thinking about senior project/design ideas. Although I will be a physicist by degree, I plan on pursuing graduate school in an engineering field (most likely mechanical, aerospace, or something closely related). I still have some time to decide what I would like to do for a senior project, but it is never too early to start planning especially in order to get extra funding. I am 99.99% sure that I would like to design and build something rather than conduct experimenting that entails pages of extensive data collection. I like the idea of assembling a complex mechanical/electromechanical system that can accomplish a certain task, but I'm having trouble coming up with any ideas... My primary interests include acoustics, piezoelectric energy harvesting, and human-powered rovers. Any suggestions would be greatly appreciated!!
