Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging
Published 2024“…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”

Investigate how the park and ride scheme serves to encourage public transport usage
Published 2011“…The current P&R system is at quite a stagnant stage whereby there is not much research done to fine tune the system. We believe that the P&R is a very good way to curb the problem of congestion in the Central Business District (CBD) area is more is done to improve the scheme to attract more users.…”
