TENS is a type of treatment that uses low voltage electrical stimulation to alleviate certain types of pain. The treatment is typically performed via a small machine, but Thimble Bioelectronics is busy designing a wearable application of the technology designed to adhere to the problem area and provide TENS treatment for the pain. Details of the exact form the TENS patch will take haven't yet been revealed, but the company says it will include integrated Bluetooth connectivity that works with an accompanying smartphone app for pain tracking and management.

As the saying goes, necessity is the mother of invention. Thimble Bioelelectrics CEO and primary founder Shaun Rahimi began work on the device when dealing with his own chronic back and arm pain. Tired of trying unsuccessfully to treat his pain with available methods that were costly, difficult or riddled with side effects, Rahimi, a medical device designer, decided to work on an alternative.

The Thimble patch sounds quite convenient, but there is some controversy as to the efficacy of TENS, and research results have varied. The technology is also already available through other small and wearable devices, such as belts and handhelds. 

Thimble was founded last year and is working to get its patch ready for release later this year. It is currently looking for developers with iOS experience to help build its mobile app. The design was a finalist in the recent Wearable Technologies Innovation World Cup.
