在一個令人興奮的發展對個人衛生技術,三星已注冊專利和美國專利商標局(USPTO)可穿戴設備專門設計來評估卡路裏攝入量。專利技術利用皮膚的光譜噪聲估計的力量消耗的熱量由一個獨立的個體。這代表了一個革命性的飛躍的科學飲食跟蹤和卡路裏含量估計。想象一個世界,手工記錄的卡路裏攝入量是過去的事了,和漂亮的設備在你的手腕毫不費力地照顧它。這可能是一個巨大的改變,它提供了保證。並使它變成一個現實的可穿戴。畢竟,目前這隻是一個專利。到目前為止,我們沒有類似的。一個例外是Healbe。他們推出了自己的卡路裏計數設備幾年前。 However, the wearable was never widely excepted. We actually reviewed Healbe GoBe 2 in 2018 and found it to be a disappointment due to its unconvincing technology. Its purpose was to alleviate the hassle of tracking calories. However, the trustworthiness of the calorie calculations provided by the device’s bio-impendance sensor was questionable. What’s more, the time delay in providing these figures made it impossible to validate the accuracy of the readings. Finally, the device was not aesthetically appealing enough to wear with short-sleeved attire due to its bulkiness. But Samsung is a much bigger name than Healbe, with more funds to dedicate to research. And its technology works in a radically different way. The patent: measuring the skin spectrum of the user The patent was submitted recently by Samsung with the USPTO goes under the number 11,653,836 . The filing describes a device that uses a fascinating method to estimate caloric intake. Typical methods for such estimates rely on biomolecule measurements such as blood glucose. But this device operates by measuring the skin spectrum of the user, which refers to the range of electromagnetic waves (light) that the skin absorbs, reflects, or emits. Image source: USPTO A spectrum measurer in the device captures this skin spectrum and a processor then interprets the noise or variation in this spectrum. By comparing this noise to a reference noise (derived from a database of spectrums from multiple users on an empty stomach), the device can estimate the calories consumed by the user. Moreover, the processor is configured to make adjustments based on other factors such as the user’s health condition and calorie consumption information. For instance, it accounts for data on past or present diseases, medication information, exercise duration, and the time interval between the end of exercise and the point of calorie measurement. This allows for a highly personalized estimation, providing users with a uniquely tailored health monitoring experience. To further amplify its functionality, this wearable device can communicate with a calorie management device. This allows the calorie management device to train the correlation model used for estimating the calories, enhancing the device’s precision over time. In a world increasingly interested in personal health, fitness, and wellness, Samsung’s new patent could be a game-changer. By providing real-time calorie consumption data, it has the potential to empower users to make much more informed decisions about their health and fitness.
