Bulk acoustic wave affinity biosensor for genetically modified organisms detection

IEEE Sensors Journal, 2003
Bulk acoustic waves have been applied as affinity sensors. In particular, a nucleic acid sensor for hybridization studies has been developed and applied for detecting DNA target sequences in solution. A DNA probe is immobilized on the sensor surface while the target sequence is free in solution; the interaction between the two complementary strands ...

MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

Advanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...

Acoustic Wave Engineering of Lamb Wave Resonators with 2D van der Waals Floating Electrode

Advanced Materials Interfaces, Volume 12, Issue 18, September 22, 2025.
AlN‐based Lamb wave resonators integrated with 2D hBN/graphene van der Waals heterostructures achieve fr exceeding 7 GHz and enhanced electromechanical coupling. The heterostructure functions as an acoustic mirror, effectively confining acoustic energy and minimizing losses, which significantly improves the Q‐factor.
