Wearable technologies (‘wearables’) describe electronic devices which can be worn on, or implanted in, the body. Wearables encompass a wide range of technologies, from pedometers which count steps to research-stage ‘smart tattoos’ which could monitor cardiac rhythm. Twenty years ago, wearables were commonly basic LCD-screened pedometers. Today, even mid-range wearables often estimate heart rate and rhythm. Options for wearables go beyond the wrist, such as the Oura ring, and the nascent emergence of a smart clothing market. Measurements which wearables record also go beyond external measurements; continuous glucose monitors are commercially available today. Wearables undertake over 35 types of measurement [1], and advanced sensors in development promise more.

可穿戴技术与健康改善

可穿戴技术（“可穿戴设备”）描述了可以佩戴或植入身体的电子设备。可穿戴设备涵盖了广泛的技术，从计算步数的计步器到可以监测心律的研究阶段“智能纹身”。二十年前，可穿戴设备通常是基本的 LCD 屏幕计步器。今天，即使是中档的可穿戴设备也经常估计心率和节律。可穿戴设备的选择超出了手腕，例如 Oura 戒指，以及新兴的智能服装市场。可穿戴设备记录的测量值也超越了外部测量值；连续血糖监测仪现在可在市场上买到。可穿戴设备承担超过 35 种类型的测量 [1]，开发中的先进传感器承诺更多。
