Muscle Strength Training and Monitoring Device Based on Triboelectric Nanogenerator for Knee Joint Surgery

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology
• Wearable Sensors

Background:

• Traditional knee surgery rehabilitation devices are often expensive or lack progress monitoring.
• Triboelectric nanogenerators (TENGs) show promise as self-sensing devices in rehabilitation.
• Limited application of TENGs in post-surgical muscle strength training.

Purpose of the Study:

• To develop an integrated, self-sensing device for knee joint muscle strength training post-surgery.
• To overcome limitations of existing rehabilitation instruments.
• To enable remote patient recovery evaluation and personalized guidance.

Main Methods:

• Innovative application of TENG self-sensing technology for knee rehabilitation.
• Development of the "Triboelectric Nanogenerator for Muscle Strength Training of Knee Joint after Surgery" (MSTKJS-TENG).
• Real-time tracking of movement quantity and quality during training.

Main Results:

• The MSTKJS-TENG is highly integrated (120 mm × 100 mm × 100 mm).
• The device accurately monitors patient movements during rehabilitation exercises.
• Facilitates remote assessment of postoperative muscle strength recovery.

Conclusions:

• The MSTKJS-TENG addresses deficiencies in current rehabilitation devices.
• Provides technical support for smart rehabilitation medicine development.
• Enables timely adjustment of training intensity and personalized patient guidance.
