ConamArray: A 32-Element Broadband MEMS Ultrasound Transducer Array
Dennis Laurijssen, Rens Baeyens, Walter Daems +1
This paper presents the ConamArray, a compact broadband ultrasound transducer array composed of 32 MEMS loudspeakers. Unlike conventional broadband transducers, which are typically…
nRTIS: Low-Cost Real-Time 3D Sonar Imaging Circular Array Supporting Beamforming for Industrial Applications
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
Conventional ultrasonic inspection systems rely on phased arrays and high-performance computing hardware, making them costly, bulky, and unsuitable for portable or embedded use. In…
High-Density MIMO Localization Using a 32x64 Ultrasonic Transducer-Microphone Array with Real-Time Data Streaming
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
In this work, we present a novel ultrasonic array system designed for high-precision localization using a large-scale MIMO (Multiple-Input Multiple-Output) architecture. The system…
PhysioEdge: Multimodal Compressive Sensing Platform for Wearable Health Monitoring
Rens Baeyens, Dennis Laurijssen, Jan Steckel +1
The integration of compressive sensing with real-time embedded systems opens new possibilities for efficient, low-power biomedical signal acquisition. This paper presents a custom…
A Wireless Self-Calibrating Ultrasound Microphone Array with Sub-Microsecond Synchronization
Dennis Laurijssen, Rens Baeyens, Walter Daems +1
We present a novel system architecture for a distributed wireless, self-calibrating ultrasound microphone network for synchronized in-air acoustic sensing. Once deployed the embedd…
Phase-Center-Constrained Beamforming for Minimizing Phase-Center Displacement
Jan Steckel, Noori BniLam
Accurate knowledge and control of the phase center in antenna arrays is essential for high-precision applications such as Global Navigation Satellite Systems (GNSS), where even sma…
