Special Issue in Micromachines: Novel Surface and Bulk Acoustic Wave Devices
The surface acoustic wave (SAW) generated by the so-called piezoelectric effect was confined to the piezoelectric substrate surface at a depth of one or two wavelengths, and hence was very sensitive towards the external perturbations. So, a SAW-based device explores a new approach to build many sensors for sensing chemical or physical measurands, such as gas, magnetic, current, pressure, and gyroscope. Larger sensitivity, fast response, low power consumption, and small size were achieved from the sensor prototypes. Another outstanding property is that they work without a battery and wireless interrogation, as they are connected only by a radio frequency link to a transceiver. This feature makes it very promising in extreme or harsh or unattended scenarios. Many great jobs towards the wireless and passive SAW-based sensors were reported in recent literature. We are interested in articles that explore wireless and passive SAW sensors. Potential topics include, but are not limited to, the following:
- Wireless and passive SAW physical sensors (temperature, pressure, strain, torque…)
- Wireless and passive SAW gas sensors
- Design theory of wireless SAW sensors
- Piezoelectric materials of wireless SAW sensors

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
