Nonlinear behaviour for acoustic systems is readily measured at high acoustic pressures in gasses or bulk materials. However, at low acoustic pressures nonlinear effects are not commonly observed. We find that by phase structuring acoustic beams, one

Video capsule endoscopy (VCE) is now a clinically accepted diagnostic modality in which miniaturized technology, an on-board power supply and wireless telemetry stand as technological foundations for other capsule endoscopy (CE) devices. However, VCE

Wireless capsule endoscopy has been used for the clinical examination of the gastrointestinal (GI) tract for two decades. However, most commercially available devices only utilise optical imaging to examine the GI wall surface. Using this sensing mod

Ultrasound capsule endoscopy (USCE) has attracted increased interest recently. In order to image the walls of the gastrointestinal (GI) tract with USCE efficiently, both high-frequency ultrasound (i.e. microultrasound) imaging and good acoustic coupl

Lead zirconate titanate (PZT)-based piezoelectric micromachined ultrasonic transducers (PMUTs) for particle manipulation applications were designed, fabricated, characterized, and tested. The PMUTs had a diaphragm diameter of 60 $\mu \text{m}$ , a re

Acoustic angiography (AA) using dual frequency (DF) ultrasound systems enables high-resolution and high-contrast imaging of the microvasculature within tissue. AA has been used to detect changes in vasculature due to cancerous tumours, and it has the

Diagnostic endoscopy in the gastrointestinal tract has remained largely unchanged for decades and is limited to the visualization of the tissue surface, the collection of biopsy samples for diagnoses, and minor interventions such as clipping or tissu

Sonoporation for targeted cancer chemotherapy in the liver with an external ultrasonic source is hampered by the ribs and fat surrounding the organ. Current therapies rely on array beam forming with sequential triggering of elements to spare the ribs
