Play for health benefits with the Walnut Personal Health Fidget Toy. Inspired by traditional walnut massage balls, this concept works as a personal device to help you stay on top of your health. Utilizing integrated infrared technology, the Walnut can monitor blood sugar levels. Hidden inside the personal health fidget toy are two infrared sensors. In addition, the sensors inside the device monitor hand-shaking and grasping power. Likewise, it relays the information back to the app for well-organized data collection. The app makes it easy to check your hand tremor, grasping power and blood glucose level. Moreover, its subtly textured surface helps improve blood circulation and stimulate the hand. Eliminating the need for collecting blood, the Walnut offers a painless, hygienic and more convenient alternative.
