A love wave sensor for (bio)chemical sensing in liquids
Sensors and Actuators A: Physical, 1994Abstract It has been shown recently that a properly designed Love wave sensor is very promising for (bio)chemical sensing because of its high sensitivity. Furthermore, it is well known that a Love wave has a pure shear horizontal polarization and therefore no elastic interaction with an ideal liquid.

Surface Acoustic Love Waves Sensor for Chemical and Electrochemical Detection
Volume 2: Automotive Systems, Bioengineering and Biomedical Technology, Fluids Engineering, Maintenance Engineering and Non-Destructive Evaluation, and Nanotechnology, 2006The present work is an experimental study of shear horizontal surface acoustic wave (SH-SAW) miniaturized sensors which offer a high potential for electrochemical applications in liquid environments and in real-time. Our devices consist of a 42° rotYX lithium tantalate (LiTaO3) substrate coated with an SU8 photoresist polymer in order to produce ...

A love-wave sensor for direct detection of biofunctionalized nanoparticles
2009 IEEE International Frequency Control Symposium Joint with the 22nd European Frequency and Time forum, 2009In this work, we have designed and manufactured Love wave sensors equipped with a liquid cell for the detection of bio-functionalized nano-particules in water. Measurements using these devices are based on the determination of velocity and propagation loss changes of a guided acoustic shear wave generated by Inter-Digital Transducers (IDTs) patterned ...

Array of Love-wave sensors to detect CWA low-levels
AIP Conference Proceedings, 2011Different Love‐wave sensors have been developed in order to detect low‐levels of chemical warfare agents for security applications. The different types of sensors have been realized using quartz and LiTaO3, as piezoelectric substrates, and SiO2 and Novolac, as guiding layers.

Design and fabrication of Love-wave sensors: An experimental study
Proceedings of the 8th Spanish Conference on Electron Devices, CDE'2011, 2011In this work a Love-wave device based on Quartz/SiO 2 has been developed considering some aspects in the design and the fabrication, in a manner that twelve different designs have been fabricated and studied their frequency response. This has allowed us to choose the most suitable device configuration in order to use it as sensor in a gas or and ...
