These material systems are created via integrating mechanical metamaterials, digital electronics and nano energy harvesting (e.g. triboelectric, piezoelectric, pyroelectric) technologies. Electronic mechanical metamaterials hold the potential to function as digital logic gates, paving the way for the development of mechanical metamaterial ...
Piezoelectric polymers (PVDF, 240 mV-m/N) possess higher piezoelectric stress constants (g 33), an important parameter in sensors, than ceramics (PZT, 11 mV-m/N), which show that they can be better sensors than ceramics. Moreover, piezoelectric polymeric sensors and actuators, due to their processing flexibility, can be readily manufactured ...

Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow. Piezoelectricity (/ ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) [1] is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in ...
His models have optimized acousto-optic modulators, improving frequency stability and stress performance. His work on anisotropic and piezoelectric materials has been significant in advancing phononic crystals for sound wave control in periodic structures, with applications in signal processing, wave filtering, and next-generation metamaterials.
Metamaterials are under consideration for many applications. [81] Metamaterial antennas are commercially available. In 2007, one researcher stated that for metamaterial applications to be realized, energy loss must be reduced, materials must be extended into three-dimensional isotropic materials and production techniques must be industrialized ...
His publications are mostly in the areas of dynamics, vibration, and wave propagation involving smart materials and metamaterials. [3] Erturk made fundamental contributions in the field of energy harvesting from dynamical systems. His distributed-parameter piezoelectric energy harvester models [4] [5] have been
The introduced piezoelectric field is perpendicular to electron transport direction, just like applying a gate voltage in the traditional field-effect transistor. Thus the electron transport properties will also be changed. [10] The materials for piezotronics should be piezoelectric semiconductors, [10] such as ZnO, GaN and InN.
