Over the past decade, wearable technology such as smart wristbands, watches, rings, and patches have gained immense popularity. According to The Economist, smartwatches are catching on as fast as early mobile phones in the United States, and the most recent study on wearables estimates that about one in four Americans owns a smartwatch or fitness tracker. Wearables have successfully entered the mainstream, and their popularity doesn't seem to be slowing down anytime soon. In 2021, the global wearables market was valued at $116 billion, and analysts forecast it will grow to $265 billion by 2026. The success of these devices is primarily due to the insights they offer users about their health.

Nair's prototype neuromodulation device stimulated nerves with electrical pulses through the skin to improve nerve function. After testing it on himself to ensure the device was safe, Nair asked his mother to try it. "She had given up hope because she had suffered for more than a year, and nothing was working," says Nair. His mother agreed to give his device a try. "She was a little disheartened when she couldn't feel anything the first time she tried it," says Nair. "For the first four weeks, she didn't have any kind of reaction to the neuromodulation stimulus. Then her legs started to respond."
