Alper Erturk (born April 3, 1982) is a mechanical engineer and the Woodruff Professor in the George W. Woodruff School of Mechanical Engineering at Georgia Institute of Technology. [1]
Erturk leads the Smart Structures and Dynamical Systems Laboratory [2] at Georgia Tech. 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 widely used by many research groups. He was one of the first researchers to explore nonlinear dynamic phenomena for frequency bandwidth enhancement in energy harvesting, specifically by using a bistable Duffing oscillator with electromechanical coupling, namely the piezomagnetoelastic energy harvester. [6] His early energy harvesting work also included the use of aeroelastic flutter to enable scalable airflow energy harvesting through piezoaeroelastic systems. [7] His collaborative work on flexoelectricity [8] established a framework to exploit strain gradient-induced polarization in elastic dielectrics for enhanced electricity generation at the nanoscale. [9]
Erturk's group also contributed to smart material-based bio-inspired aquatic locomotion by developing the first untethered piezoelectric swimmer [10] and explored fluid-structure interaction via underwater actuation of piezoelectric cantilevers. [11] [12] Their recent efforts resulted in multifunctional piezoelectric concepts for bio-inspired swimming and energy harvesting. [13]
Another research topic explored by his group is wireless power and data transfer using ultrasound waves. [14] [15] More recently, Erturk and collaborators investigated the leveraging of guided waves in cranial and transcranial ultrasound. [16] [17] [18]
Erturk and collaborators also explored metamaterials and phononic crystals for elastic and acoustic wave phenomena. They developed and experimentally tested some of the first 2D elastic wave [19] [20] and 3D bulk acoustic wave [21] [22] lenses, locally resonant metamaterial-based structural theories and experiments, [23] including programmable piezoelectric metamaterials and metastructures.
