Design
Bionic Design: The Intelligent Bionic Prosthetic Back Hand features an ergonomic design tailored to the size and shape of Asian hands. Its elegant appearance, with smooth, natural lines in the fingers and palm, closely mimics the look and feel of a real hand.
Material Selection: The internal structure is constructed from durable, lightweight materials such as aluminum alloy, zinc alloy, and stainless steel, ensuring the strength and stability of the bionic hand, capable of withstanding the forces and pressures of daily use. The silicone elastic fingertips and half-palm glove provide a soft touch and excellent friction, ensuring a more secure grip and increased comfort.

Technical Principles
Myoelectric sensing technology: Utilizes an array of non-invasive myoelectric nerve signal sensors to detect the weak electrical signals generated by muscle contraction at the distal end of the residual limb. These sensors accurately capture the bioelectrical signals emitted by the muscles when the user intends to perform an action, providing a data foundation for subsequent movement recognition and control.
Artificial intelligence pattern recognition algorithms: Analyze and process the myoelectric signals collected by the sensors. Using AI technologies such as deep learning, these signals are converted into computer-understandable commands, accurately identifying the user’s intended movements, such as grasping, reaching, and pinching, achieving precise conversion from bioelectrical signals to specific movement commands.
Gesture engine technology: Based on the recognized movement intent, the bionic hand’s mechanical structure drives the corresponding movement. Through precision motors, connecting rods, and other transmission devices, these commands are converted into precise movements of the fingers, wrist, and other parts of the body, enabling the bionic hand to perform various movements with the same dexterity as a real hand. Product Features
Compact Size: Available in two sizes: standard and small. The standard size measures 179mm from the middle fingertip to the wrist, with a maximum palm width of 83mm. The small size measures 157mm from the middle fingertip to the wrist, with a maximum palm width of 76mm. The overall compact design makes it suitable for a variety of wearers.
Powerful and Fast: Fully opening and closing of the fingers takes just 1 second. Maximum active push force with the index fingertip is ≥ 0.45 kgf, maximum active push force with the thumbtip is ≥ 1.1 kgf, and maximum active pinch force with two or three fingers is ≥ 1.1 kgf. The maximum lifting capacity is up to 30 kg, meeting various strength requirements in daily life. High Degrees of Freedom: Powered by five linear motors, the fingers can bend independently, the thumb’s side-to-palm position is adjustable, and it features a passive wrist strap lock. The wrist rotation range is ±175 degrees, the thumb’s side opening and closing angles are 0-31 degrees, and the palm opening and closing angles are 0-50 degrees, providing a wide range of motion freedom and enabling a variety of complex gestures.

Rich Gestures: 27 common gestures are pre-programmed, including grasping a toothbrush, lacing and unlacing shoes, keyboard tapping, side gripping, side pinching, pointing, supporting, and lifting. These gestures cover a wide range of personal care, home life, and workplace scenarios, helping individuals with upper limb loss achieve their daily needs independently.

Packing

We use high-strength environmentally friendly materials and combine scientific design to ensure that cargo is protected from risks,such as impact and moisture during transportation. Whether it is shockproof, moisture-proof or customized packaging, we focus on details to meet the special needs of different commodities.

Delivery

Whether it is sea transportation, air transportation, rail transportation or multimodal transportation. We are committed to tailoring the best transportation plan for our customers to ensure that every piece of goods can reach the destination in the most economical and fastest way, helping your global business to be unimpeded.

Production Process

1. Production specialization: Each step of the process is completed by a specific machine, avoiding the confusion of
cross-operation, accurately controlling the processing quality of each link, and reducing the impact of human errors on product consistency.
2. Process integrity: The complete assembly line design ensures the continuity of the production process, forming a
closed loop from single component processing to final assembly and packaging, reducing the risk of process interruption and improving overall production efficiency.
3. Timely delivery: The full chain from production to delivery is ready, which means that it can respond quickly to order
needs,shorten the cycle from customer ordering to receiving products, and enhance market competitiveness.

Quality Inspection

As soon as the product comes off the production line, it immediately enters the “intelligent detection matrix” constructed by professional quality inspection equipment: the high-precision visual system is like a “fiery eye”, scanning the product surface frame by frame with micron-level resolution to capture even hair-like flaws; the pressure sensor device is transformed into a “tactile expert”, simulating extreme usage scenarios to apply dynamic loads and verify structural stability. Each test data is
imported into the central quality control system in real time, and compared with the preset quality benchmark at the millisecond level. Once a deviation occurs, the system will automatically trigger a graded warning – slight deviations are calibrated by the equipment itself, and critical value fluctuations are simultaneously pushed to the terminal of the quality inspection engineer, forming a double line of defense of “equipment full-time monitoring + manual precise review”. The whole process is like a “rigorous physical examination” tailored for the product, from appearance to performance, from material to precision, to build a comprehensive quality defense line, so that every product shipped from the factory arrives in the hands of users with “quality”.
