Bond Ring™
A product of Wilder Tech Inc. © Wilder Tech Inc. All key innovations in the Bond Ring™ and its design are patent-pending with the USPTO. Bond Ring™, TrueTemp™, LifeDrive™, Bionic Feedback™, Ballistic Sampling™, Future on Your Finger™, and Pinnacle of Wearable Advancement™ are registered trademarks.
^The Bond Ring is not a medical device and is not intended to diagnose or treat any medical condition. All features are designed solely for wellness purposes. However, the Bond Ring is progressing toward clinical trials and may eventually receive FDA clearance to diagnose various conditions, potentially transitioning to a medical device in the future. When referring to clinical-grade sensors, we mean certified and tested sensors designed for medical devices; this does not classify the Bond Ring as a “clinical” or “medical” device. Our primary objective is to deploy the best suite of sensors to enhance user awareness of personal wellness and vital body metrics.
*Sleep apnea is classified as a medical condition. Bond Ring and Bond Ring Evo are not medical devices and are not intended to diagnose or treat sleep apnea. The sensors measuring respiration rate and blood oxygen levels during sleep are designed exclusively for insight and awareness. If you suspect you have symptoms of sleep apnea, consult your primary care physician, a sleep specialist, or another qualified medical professional for diagnosis and treatment. This statement does not constitute medical advice.
¹When we refer to “perpetual” or “maintaining perpetuality,” we do not imply that the device can operate indefinitely without any external energy under all circumstances. The LifeDrive modules in devices such as the Bond Ring FE and Bond Ring PRO battery packs generate power from ambient light and/or the natural flow of body heat to the surrounding environment (or vice versa). These rings utilize intelligent power-management algorithms that enable them to operate for up to three months in “maintain perpetuality” mode, even without exposure to light and/or when worn in environments that remain within ±5°C of body temperature. However, such conditions are considered highly unrealistic in typical use. If you anticipate wearing the Bond Ring Perpetual products in environments matching these parameters, please note that the rings/battery packs will cease functioning after approximately two to three months and will require exposure to natural light to recharge. Depending on the setting the Bond Ring PRO can easily run through the battery pack in less than 12 hours and hence we do not recommend using LifeDrive Battery Packs for such heavy use and it would be recommended to use standard or plus battery pack(s).
¹Bond Ring Evo, unlike Bond Ring, measures body composition across the upper body using our proprietary algorithm to estimate equivalent variations in body composition. Measurements from both Bond Ring and Bond Ring Evo are not intended for medical diagnosis or treatment.
