Conductive gels have wide applications in many cutting-edge technologies and industrial fields. Their core advantage lies in combining conductivity with the soft, deformable properties of gels, adapting to diverse needs from biomedicine to flexible electronics.
1. Biomedicine and Health Monitoring
EEG/ECG/EMG Detection: Replacing traditional metal electrodes, conductive gels are used as wet electrodes, reducing skin irritation, improving signal stability, and are suitable for long-term physiological monitoring.
Wearable and Implantable Bioelectronics: Used in ECG patches, brain-computer interfaces, and other devices to achieve flexible adhesion to human tissue, reducing the risk of immune rejection.
Smart Wound Dressings: Possessing functions such as electrical stimulation to promote healing, antibacterial properties (e.g., releasing silver ions), and on-demand drug release (e.g., electrically controlled insulin release), they are particularly suitable for the treatment of chronic diabetic wounds.
2. Flexible Electronics and Wearable Devices
Electronic Skin and Tactile Sensors: Simulating the sensory capabilities of human skin, used in prosthetic feedback and rehabilitation robots, they can sensitively detect changes in pressure, strain, and temperature.
Flexible Energy Storage Devices: Serving as electrolytes in supercapacitors or batteries, these devices combine conductivity and mechanical flexibility to support wearable energy systems.
Stretchable Circuits and Connectors: Enable stable conductive connections in dynamically bending areas (such as joints), suitable for flexible displays and smart clothing.
3. Tissue Engineering and Neural Repair
Cardiac Patches: Conductive hydrogel scaffolds are used to culture cardiomyocytes, promoting synchronous electrical signal transmission and repairing cardiac function after myocardial infarction.
Neural Conduits and Spinal Cord Repair: Guide axonal regeneration, apply weak electrical stimulation to promote Schwann cell proliferation and myelin formation, and accelerate the recovery of nerve function.
