hybrid sensorTranscutaneous Electrical Nerve Stimulation

Transcutaneous Electrical Nerve Stimulation or TENS is a process where electrical pulses are sent through electrodes on the skin to stimulate muscles under the skin. In contrast to FES which is used for rehabilitation and retaining muscle function in case of injury, TENS is used for pain relief.

The applications where TENS has shown to be useful for pain relief are quite varied. TENS has been used to treat both acute and chronic pain in various places of the body. Even though TENS devices tend to be available as consumer products, it is always a good idea to consult your physician or a trained professional before use of these devices.

Technical Challenges:

TENS electrodes provide a few different challenges compared to recording electrodes. For most recording electrodes, silver/silver chloride conductive traces combined with hydrogel are the golden standard. The problem is that when you send an electrical signal through the electrode strong enough to provide stimulation, this tends to cause a reaction between the chloride and the hydrogel. The result of this can be yellow spots on the skin and irritation.

Luckily Screentec has materials that prevent these problems as well as many other solutions to make sure that your electrodes are reliable and of good quality.
