近年来，可穿戴系统变得越来越流行，特别是在健康传感应用中，它们可以对患者进行长期监测。然而，这些设备中的大多数都是由电池供电的，并且需要定期充电，这不仅造成了用户依从性的问题，而且还可能错过关键的感知事件。能量收集提供了一种有前途的解决方案，可以延长电池的寿命，甚至完全取代它们，以实现连续的自供电操作。热电发电机（TEG）通过收集人体产生的热量为自供电可穿戴设备提供了潜力。然而，环境动态和人类行为-特别是TEG周围的气流-会影响可收集的能量，从而导致高度动态的能源，这可能会影响自供电操作的潜力。在这个项目中，我们设计了一个可穿戴数据收集平台，记录环境和行为数据，集中在手腕周围的气流。该平台收集基于真实世界环境和行为动态的痕迹，从而能够探索能量收集动态和TEG驱动的可穿戴应用的潜力。
Wearable systems have become popular in recent years, especially in health sensing applications where they enable long-term monitoring of patients. However, the majority of these devices are powered by batteries and regularly need to be recharged, creating not only issues of user compliance but also the potential for missing critical sensing events. Energy harvesting presents a promising solution to extend the lifetime of the batteries or even completely replace them for continuous self-powered operation. Thermoelectric generators (TEGs) provide the potential for self-powered wearables by harvesting the heat generated by the human body. However, environmental dynamics and human behavior - specifically airflow around the TEG - affects the harvestable energy, resulting in a highly dynamic energy source that can affect the potential for self-powered operation. In this project, we designed a wearable data collection platform that records environmental and behavioral data with a concentration on airflow around the wrist. This platform collects traces based on real-world environmental and behavioral dynamics, enabling exploration of energy harvesting dynamics and the potential for TEG-powered wearable applications.
