Product Introduction
Product Introduction
Thank you for choosing our KT-H001 intelligent myoelectric prosthetic hand. This product is an intelligent prosthetic hand controlled based on myoelectric signals, designed for upper limb amputees. It detects weak electrical signals from the residual limb muscles to control actions such as opening, closing, and grasping of the prosthetic hand, providing a user experience with motion functionality close to that of a natural hand.
Paired with our self-developed dedicated APP, it offers a user-friendly and portable control system for myoelectric prosthetic hand users. Through the APP, users can view usage data, manage the device, and redeem points, among other functions. Additionally, the APP allows users to monitor and adjust the signal status and functionality of the myoelectric prosthetic hand to enhance the user experience.
With proper training, disabled users of this product can perform daily activities such as drinking water, eating, and dressing, significantly improving their quality of life. The economically practical positioning of the product aims to benefit more individuals with disabilities in meeting their daily needs.
PRODUCT FUNCTION
Producr Function
In terms of the functionality of the movements, it can specifically achieve seven sets of actions: pinching thin sheet-like objects with two fingers, grasping irregular objects with three fingers, holding ordinary objects with a three-finger pinch, gripping tools with all five fingers, coordinating four fingers and the thumb to grasp/release items, flexing and extending the wrist to swing the palm back and forth, and internally/externally rotating the wrist to allow slight rotation of the palm.
Three-Finger Grasp of Irregular Objects
With sensitive feedback from thumb and index finger sensors, coordinated envelopment by the middle finger, and support from the remaining fingers, the prosthesis can precisely handle irregular objects like eggs with accurately controlled force.
Three-Finger Grip for Common Objects
The robust coordination of the thumb, index, and middle fingers enables daily actions such as holding a spoon, allowing users to effortlessly enjoy eating and drinking.
Five-Finger Grasp for Everyday Items
Using the combined force of all five fingers, the hand can grip lightweight tools like brooms or watering cans, making simple household tasks achievable. It also securely holds items such as cups and toothbrushes, promoting self-reliance and confidence in daily life.
Five-Finger Lifting with Upward Force
By applying simultaneous upward force with all five fingers, the prosthesis can lift objects weighing up to 3 kg. This not only aids in effective arm rehabilitation training but also assists in performing light hand tasks, such as carrying a tray or holding books.
Wrist Flexion and Extension for Hand Tilting
Flexion and extension of the wrist enable hooking and raising motions of the hand. Combined with hand movements, this offers users greater convenience in various activities.
Wrist Internal and External Rotation for Minor Hand Rotation
Internal and external rotation of the wrist allow slight turning of the palm, making actions like pouring tea and water easy to accomplish without relying on compensatory elbow movements.

Human-centered Design
Rooted in the ADL assessment scale standards, the product effectively helps users increase their brethren index by over 25 points. To assist individuals with upper limb disabilities in regaining daily living abilities such as self-feeding and personal hygiene, the design focuses on optimizing high-frequency gripping motions in real-life scenarios. This enables users to independently perform a variety of common daily actions while also restoring their capacity for simple productive tasks, thereby helping them reclaim their dignity in life.
01
Bio-inspired Design
The overall appearance is based on statistical data from national hand shape standards for adults, incorporating regression equations for hand control dimensions and hand type coverage rates to determine the final product hand shape. This ensures compatibility with diverse hand types across different regions, genders, and individual variations. Additionally, the design draws extensively from scientific principles of hand movement kinematics to simulate motions, employing highly bionic design to align with the biomechanical characteristics of the human body.
02
Universal Practicality
From the initial design phase, cost control has been a priority, ensuring the retail price remains affordable for a broader user base. Without significant compromises in performance, the product offers lower usage and maintenance costs while maintaining high product quality and functionality.
03
Lightweighting
The structural components made of 6061 aluminum feature an integrated hollow design and anodizing treatment, achieving weight reduction while enhancing corrosion resistance. High-performance steel used for mechanical structural requirements undergoes heat treatment to improve structural strength. The center of gravity for each component is positioned closer to the proximal end, with the motor’s center of gravity near the socket. The hand module weighs no more than 300 grams, leveraging joint leverage principles to reduce arm load and provide a more comfortable wearing experience.
04
Greater Convenience
With user-friendly operation and a streamlined APP management system, the product delivers a hassle-free experience that simplifies daily life. The hand cover is made of resilient silicone that resists stains, paired with a desert gray color scheme designed for easy maintenance. The surface is simple to clean, ensuring the wrist section remains fresh and tidy, allowing the product to seamlessly integrate into users’ lives.

Bionic Hand Design
01
Bionic Hand Design
The bionic-shaped fingers are designed and adjusted based on 32 dimensional parameters—including palm length, thickness, width, and circumference—to closely match the hand sizes of the majority of the population and align with the movement logic of a natural hand. The hand cover is made of high-performance, tear-resistant flexible silicone material, offering advantages such as stain resistance, practicality, high aesthetic acceptance, a tech-inspired design, and durability.
A stable structural base is formed with high-density, highly resilient sponge filler. By further mimicking the anatomical features of the thumb web and thenar eminence, the prosthetic hand enhances its range of achievable motions, supporting various grasping, releasing, and holding actions.
02
Bionic Wrist Design
02
Bionic Wrist Design
The bionic intelligent myoelectric prosthetic hand can be equipped with a bionic wrist joint tailored to the user’s residual limb length and usage habits. The wrist joint’s appearance is designed to reflect anatomical characteristics. In a static relaxed state, the wrist assumes a typical natural extension posture. In active control mode, it enables voluntary flexion-extension and internal-external rotation, closely replicating the movement patterns of a natural human wrist, thereby ensuring both aesthetic appeal and biomechanical rationality.
03
Comprehensive Grasping Function
03
Comprehensive Grasping Function
While enabling the thumb to cooperate with the four fingers at different opening angles for grasping objects of various shapes, the adjustment mechanism has been optimized based on real-world scenarios. This allows for enveloping and adaptive grasping of sheet-like objects and irregular items of varying sizes relative to the thumb web space.

High-Precision Myoelectric Signal Sensing
04
High-Precision Myoelectric Signal Sensing
The sensing and recognition system is equipped with an industrial-grade STM32 low-power chip, a four-channel surface EMG sensor matrix, a high-density lithium battery, and an SMBus battery management module. It enables rapid sensing, noise reduction, and identification of muscle movement physiological data, along with signal modulation and processing for accurate transmission of control commands. This ensures efficient recognition and execution of hand and wrist movement commands, achieving natural human-machine interaction.
05
Intelligent Tactile Sensing Module
05
Intelligent Tactile Sensing Module
Tactile sensing modules are integrated into the fingertips of the index finger and thumb. Each module adopts a pre-shell design combining "skin-friendly liquid silicone + 2×2 matrix thin-film electrode sheets," and includes a temperature sensor for high-frequency self-calibration to actively compensate for temperature drift caused by environmental changes. This provides highly sensitive normal force pressure feedback for objects of different hardness levels, offering convenience in both daily living and certain work scenarios.
