A transparent piezoelectric metasurface (PM) is proposed to achieve various motion modes with high strains in a wide frequency range. The PM is designed with ten units of [001]-poled PIMNT single crystals, enabling linear motions along X-, Y-, and Z-axes, rotary motions around X-, Y-, and Z-axes, and coupled modes. An adaptive lens (ALENS) based on the PM can adjust focus (AF) and provide optical image stabilization (OIS) with large displacements (5.05 μm along Y-axis) and tilt angles (44.02° around Y-axis). The PM offers a wide focal length range (35.82 cm to ∞) and high performance. The PM is fabricated using transparent PIMNT single crystals and soft PZT ceramics, with simulations and experiments confirming its effectiveness. The PM-based ALENS demonstrates high control accuracy, operation reliability, and long-term stability. It can achieve AF and OIS functions with a simple structure, making it suitable for adaptive optics systems. The PM-based ALENS has applications in optical systems, including AF, pitch, roll, and coupled modes. The study highlights the potential of the PM for advanced piezoelectric devices in industry.A transparent piezoelectric metasurface (PM) is proposed to achieve various motion modes with high strains in a wide frequency range.
