These adhesive components are essential for transcutaneous electrical nerve stimulation (TENS) therapy. They serve as the conductive interface between the TENS device and the skin, facilitating the transmission of low-voltage electrical currents to targeted nerve fibers. This transmission is typically achieved through a hydrogel layer on the pad’s surface.
Effective current delivery is crucial for pain relief and muscle stimulation, the primary therapeutic goals of TENS. Without these adhesive interfaces, the electrical impulses would not reach the underlying nerves, rendering the therapy ineffective. Historically, reusable electrodes made of various conductive materials like carbon rubber were used, requiring conductive gels or moistened sponges. Modern disposable adhesive versions offer improved convenience and hygiene.
