Market size and current status: A market worth hundreds of billions of yuan, with core components urgently needing breakthroughs!

Embossed intelligent robots are experiencing explosive growth, with the global market size projected to exceed hundreds of billions by 2030. As the core execution unit, the driving technology of finger joints directly determines the robot's flexibility, precision, and response speed. However, traditional motor and hydraulic drive solutions suffer from bottlenecks such as large size, slow response, and complex control, highlighting the urgent need for more efficient solutions in the industry!

Industry pain points vs. the disruptive advantages of piezoelectric ceramics

❌ Pain points of traditional solutions:

Electric motor + reducer: Large size and weight, making precise operation difficult.

Pneumatic/hydraulic drive: Complex system, high energy consumption, and high maintenance costs.
Insufficient response speed: Difficult to meet the needs of high-frequency tactile feedback or rapid grasping.

✅ Breakthrough advantages of piezoelectric ceramics:

Nanoscale precision: Directly converts electrical signals into mechanical displacement using the inverse piezoelectric effect, achieving nanoscale control precision.

Millisecond-level response: High-frequency drive (>1kHz), far exceeding traditional motors.

High power density: Small size and light weight, perfectly suited for the compact design of biomimetic joints.

Zero-energy self-locking: Maintains position after power failure, energy-saving and safe!

How to select piezoelectric ceramics? Key parameters at a glance

Key considerations for robot joint applications:

Dynamic piezoelectric coefficient (d₃₃*): Determines displacement output capability. For example, our company's piezoelectric ceramic material YGP-51 achieves a strain of 0.15% under a 20kV/cm field strength, meeting the displacement requirements of various application scenarios.

Electromechanical coupling coefficient (kp): ＞0.6。

Fatigue resistance: Over one billion cycle life, suitable for high-frequency operation requirements.

Low voltage drive: Multilayer stacking technology (MLA) achieves an operating voltage of <100V.

Our solution: Tailor-made for embodied intelligence.
