This work presents the design, fabrication, and validation of a surface acoustic wave (SAW) sensor utilizing ladder-type interdigital transducers (LIDTs) and direct group delay measurements. By exploiting the LIDT multi-subchannel structure, sensing and reference channels are integrated into a single device, significan...

The integration of polydimethylsiloxane (PDMS) microstructures with surface acoustic wave (SAW) devices requires controlled mechanical attachment to piezoelectric substrates, as mechanical boundary conditions directly influence the heating rate through acoustothermal energy dissipation. In this work, we propose a novel...

This work presents the design, fabrication, and validation of a modular, miniaturized cell culture platform manufactured by 3D laser sintering using polyamide (PA12). The platform integrates real-time control of the internal atmosphere and temperature, provides access for bright-field optical microscopy, and incorporat...
