Cur is a wearable TENS (Transcutaneous Electrical Nerve Stimulation ) therapy device that uses low voltage electric current to relieve pain more effectively.

The device has rechargeable battery and can work for up to 3 hours. The device uses adhesive gel pads that can be stuck to the back or wrapped around arm and leg.
The device can work continuously for 60 hours when used with powered carrying case. The device can also be programmed wirelessly through a smartphone.
Cur is not a cure for chronic pain but can provide relief from pain. “The user can wear cur at work or during a run without asking for help from a professional,” said, Cur founder Shaun Rahimi, a biomedical engineer.
