Advanced Sensor Integration and Data-Driven Adaptability in the TC Bionic Hand

In collaboration with our partners, we have developed the TC Bionic Hand, designed to provide patients with multi-grip versatility and adaptive control. With five intuitive, easily selectable grip patterns, this prosthesis enables users to perform daily tasks with enhanced precision and ease. Integrated visual, auditory, and haptic feedback through lights, sounds, and vibrations ensures that users remain constantly informed about the prosthesis’ status.

Applied Sensor Technologies

The TC Bionic Hand integrates a range of advanced sensors for precision and adaptive use.

• Electromyographic (EMG) sensors detect muscle activity and convert it into motor commands for natural control.

• Piezoresistive and capacitive pressure sensors measure grip force to ensure controlled object manipulation.

• Haptic feedback actuators simulate touch through vibration or electrical stimulation for enhanced control.

• Thermistors and infrared sensors detect temperature variations for precise environmental awareness.

• Inertial Measurement Units (IMUs) measure orientation and acceleration to support fluid movements.

• Flex sensors analyze finger and wrist positioning for more precise grip patterns.

AI and Big Data Application

The sensors are supported by AI and Big Data for optimized performance.

• Adaptive motor control through AI: Machine learning processes EMG signals and adjusts movements based on individual usage patterns.

• Automated pattern recognition: AI optimizes grip strategies by analyzing sensor feedback.

• Real-time data integration: Sensors generate continuous data for immediate responsiveness and maintenance optimization.

• Proactive error correction and predictive analysis: AI detects and corrects deviations in movement patterns.

• Cloud-based optimization: Firmware updates and performance improvements are deployed via the cloud.

Through these advanced sensor technologies and AI-driven analytics, the TC Bionic Hand offers an exceptional level of precision and adaptability.

Key features include:

• Proportional control, allowing users to regulate finger movement speed for enhanced precision

• Freeze mode, enabling the hand to lock in a specific position when needed

• Flexible thumb and wrist, improving dexterity for fine motor tasks and grasping objects at various angles

• 180-degree wrist rotation for increased flexibility in object handling

• Hook grip load capacity of up to 3 kg

• Pinch grip closure speed of 0.9 seconds, ensuring efficient object manipulation
