Abstract
This paper covers research on novel thin films with periodical microstructure—optical elements, exhibiting a combination of piezoelectric and surface plasmon resonance effects. The research results showed that incorporation of Ag nanoparticles in novel piezoelectric—plasmonic elements shift a dominating peak in the visible light spectrum. This optical window is essential in the design of optical elements for sensing systems. Novel optical elements can be tunable under defined bias and change its main grating parameters (depth and width) influencing the response of diffraction efficiencies. These elements allow opening new avenues in the design of more sensitive and multifunctional microdevices.
Highlights
A main challenge for researchers has been the design and manufacture of more efficient, reliable and accurate low-cost sensing devices
Application of nanotubes and nanofibers is one novel method for amplifying the sensing signal in immunosensors for medical purposes [5], acoustic and optical sensors used in detection of various solvents [6], novel optical pressure sensors in tactile robotic systems [7], imaging systems [8], etc
The results proved that no poling is needed for thin films when PMMA is introduced, i.e., the piezoelectric elementary cells have a uniform orientation
Summary
A main challenge for researchers has been the design and manufacture of more efficient, reliable and accurate low-cost sensing devices. Application of nanotubes and nanofibers is one novel method for amplifying the sensing signal in immunosensors for medical purposes [5], acoustic and optical sensors used in detection of various solvents [6], novel optical pressure sensors in tactile robotic systems [7], imaging systems [8], etc These sensors have had a huge impact in the food industry [9], bio-industry [10], medicine [11], environmental control [12], etc., because of their capability to continuously and reversibly give a selective and fast response to the presence of a specific compound in a complex mixture of components, without perturbing the system
