Event Detection and Classification Using Distributed Acoustic Sensors
This thesis is on the mathematics of seismic data acquisition and processing, with a particular focus on distributed acoustic sensing. Distributed acoustic sensing (DAS) is a relatively new means of seismic acquisition. It utilizes strain on a fibre-optic cable to deduce information about nearby events.

Flexible piezopolymer ultrasound transducers are engineered by tailoring the electrode–piezopolymer interface using metallic, flake‐based, and porous graphene electrodes. Laser‐induced graphene's porous structure enables polymer infiltration, strengthening interfacial coupling and enhancing piezoelectric response and acoustic output.

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
