Piezoelectric Micromachined Ultrasound Transducer (pMUT) Array for Underwater Communication KU Leuven
This project is about designing a low power and small (um range) ultrasound piezoelectric transducer for mid-range (>1meter) underwater communication. The aforesaid device has many applications, such as the exploration of inaccessible environments, bio-sensing, surface mapping, etc. The scientific approach of the project can be divided into three parts; piezoelectric material growing, fabrication of a communication module and ...
Real-time diagnostics during middle ear surgery through combination of minimally invasive floating mass transducer stimulation and laser-doppler vibrometry measurements. University of Antwerp
Active sound field and noise control in wireless acoustic transducer networks KU Leuven
The active control of sound fields using microphone and loudspeaker arrays has been an active research topic for many decades, with applications in noise control, sound zoning, etc. This PhD project aims to address the active sound field control problem in a context of wireless acoustic transducer networks, in which microphones, loudspeakers, and computational resources are spatially distributed and in-network wireless communication is ...
DSP Algorithms for Ad-Hoc Wireless Transducer Array Networks KU Leuven
The quality of a speech signal recorded through multiple microphones can be compromised by various undesired signals, including noise and reverberation, leading to diminished intelligibility. Some of these undesired signals may be generated by loudspeakers within the same acoustic environment, potentially generating acoustic echoes and/or feedback. Multi-microphone speech enhancement systems aim at suppressing or canceling these interference ...
Dynamic Modeling of Macro-Fiber Composite Transducers Integrated into Composite Structures KU Leuven
Composite structures have been already widely applied in engineering. Laminated composites using isotropic or anisotropic layers provide numerous options for designing lightweight structural components, that have high static stiffness and excellent impact resistance for automotive and aerospace products. However, lightweight structures can be susceptible to external disturbances due to mass reduction and light damping in many cases. As a ...
ULTIMO: Piezoelectric micromachined ultrasound transducers (pMUT) for the next generation of low-cost, portable and high-performance medical ultrasound imaging probes (Ultrasound Imaging on Mobile) KU Leuven
Piezoelectric Micromachined Ultrasound Transducers (PMUTs) KU Leuven
Piezoelectric micromachined ultrasound transducers (pMUTs) are nowadays replacing bulk PZT based transducers in various applications like medical imaging, finger print sensors, rangefinding. pMUTs have an edge over the conventional technology due to their small dimension, low power consumption, high element density, and easy and cheap fabrication process. In applications like brain stimulation, intravascular imaging, wearable ultrasound ...
Sensory TRP channels as key transducers in body homeostasis KU Leuven
Summary Currently, no medical intervention effectively protects cognitive function in people with dementia. A number of converging lines of research indicate a potentially transformative role for neuromodulation. We are developing a minimally invasive way to electrically stimulate the brain in order to preserve neurons in brain regions that are involved in cognitive functioning. This will delay functional decline in patients with ...
Microglia and neuroinflammation: transducers of amyloid beta toxicity in human Alzheimer’s disease KU Leuven
Alzheimer’s disease (AD) is a chronic neurodegenerative disease and is the most common form of dementia worldwide. AD is characterized by the build up of abnormal protein, in the form of amyloid beta plaques and tau tangles. AD is accompanied by changes in the immune cells of the brain, the microglia. This inflammation in the brain is referred to as neuroinflammation, which may be a simple consequence of damage to nerve cells or may ...
