ibutton-left-nondominant-upper-arm-cotton-sports-wristband-radial-artery-ventral-interior-5min-v2

Skin temperature using a Maxim Thermocron iButton DS1925L set at a resolution of one sample every 5 min (max resolution) and temperature resolution of 0.0625°C (max resolution), placed on the radial artery on the forearm (between elbow and wrist, about in the middle with a slightly changing position regularly to avoid skin damage due to continuous skin obstruction and warmth), by being attached with a velcro to the interior of a cotton sports wrist band. This sensor should allow to capture circadian rhythm modulations. See the works of Dr. Antonio Martinez Nicolas for more details on wrist skin temperature rhythm and WTIO. <br> The procedure is described in: https://pubmed.ncbi.nlm.nih.gov/18761026/ <br> Part of the MyNon24Sleep v2 dataset, specifications of the study's design and wearables setup available in the Wearadian v2 project's documentation. Data starts from 2022-03-17 and will cover one whole year. Data is discontinuous, each csv file should be concatenated with the next ones based on datetime to get the full dataset. <br> This dataset can be used alone or in combination with ibutton-left-nondominant-upper-arm-cotton-sports-wristband-dorsal-interior-5min-v2 to regress dorsal skin temperature. There are no recordings for ambient temperature in Wearadian v2. <br> The maximum number of samples seems to be 62720, which is about about 6-7 months of continuous data recording maximum per run. So it's necessary to clear the sensor's data before collecting a new period. <br> Note that the datetime in the filename is in US format: monthdayyear. <br>

采用Maxim Thermocron iButton DS1925L采集皮肤温度，该传感器设置为每5分钟采样一次（最高采样分辨率），温度分辨率达0.0625℃（最高温度分辨率）。传感器佩戴于前臂桡动脉处（肘与腕之间的大致中点位置），为避免持续压迫皮肤及局部温热引发皮肤损伤，需定期小幅调整传感器位置；通过魔术贴将其固定于棉质运动腕带内侧。
该传感器可用于捕捉昼夜节律的调节变化。如需了解腕部皮肤温度节律及WTIO的更多细节，可参考Antonio Martinez Nicolas博士的相关研究成果。

本数据集属于MyNon24Sleep v2数据集的一部分，该研究的设计方案与可穿戴设备部署规范可查阅Wearadian v2项目的文档。数据采集始于2022年3月17日，计划覆盖一整年时长。数据存在间断，需根据时间戳将所有CSV文件按顺序拼接，以得到完整数据集。
本数据集可单独使用，或与ibutton-left-nondominant-upper-arm-cotton-sports-wristband-dorsal-interior-5min-v2数据集结合，用于背部皮肤温度的回归分析。Wearadian v2项目未采集环境温度数据。
单批次连续采集的最大样本量约为62720条，对应约6至7个月的连续记录时长。因此，在开展新一轮数据采集前，需清空传感器内的原有数据。
请注意：文件名中的日期时间采用美式格式：月日年（monthdayyear）。
