Special Issue Information

Dear Colleagues,

Over the increasing demand of sensors, there is a need for development of functional materials which can be efficient and safe for various sensing application. Functional materials integrated sensors can be used to monitor food safety, infrastructure, smart home, agricultural, and can also be used for biomedical applications such as virus detection in COVID-19 etc. Functional materials are very susceptible to external environmental changes, such as pressure, temperature, relative humidity, and are suitable for sensing applications.  The future of functional materials is strictly dependent on the availability of optimized synthesis techniques that allow the processing and manipulation of properties in a precise manner. This special issue encourages authors, from academia and industry, to submit new research results about technological innovations and novel applications for sensors. The various design of sensors followed by their experimental results integrated with functional materials along with their challenges will be also be encouraged.

The Special Issue topics include, but are not limited to:

  • Functional materials synthesis techniques and properties
  • Characterization techniques of functional materials
  • Characteristics of functional materials in the influence of various physical parameters
  • Design of various sensors including chipless RFID sensors
  • Sensors integrated with functional materials
  • Fabrication, and performance of various sensors

Here, a static tactile sensing scheme based on a piezoelectric nanofiber membrane, prepared via the electrospinning method, is presented. When the nanofiber membrane is kept under a constant vibration, an external contact onto the membrane will attenuate its vibration. By monitoring this change in the oscillation amplitude due to the physical contact via the piezoelectrically coupled voltage from the nanofiber membrane, the strength and duration of the static contact can be determined. The proof-of-concept experiment demonstrated here shows that the realization of a static tactile sensor is possible by implementing the piezoelectric nanofiber membrane as an effective sensing element.

Photoresist is the key material in the fabrication of micropatterns or microstructures. Tuning the surface wettability of photoresist film is a critical consideration in its application of microfluidics. In this work, the surface wettability tuning of acrylic resin photoresist by oxygen plasma or ultra-violet/ozone, and its aging performance in different atmospheres, were systematically studied. The chemical and physical characterizations of the surfaces before and after modification show a dramatic decrease in the C–C group and increase in surface roughness for oxygen plasma treatment, while a decrease of the C–C group was found for the UV/ozone treatment. The above difference in the surface tuning mechanism may explain the stronger hydrophilic modification effect of oxygen plasma. In addition, we found an obvious fading of the wettability tuning effect with an environment-related aging speed, which can also be featured by the decrease of the C–C group. This study demonstrates the dominated chemical and physical changes during surface wettability tuning and its aging process, and provides basis for surface tuning and the applications in microfluidics.
