实际生物组织的利用(例如,猪肉样本)和组织模仿体模对于基于光学的体内数据和能量转移研究至关重要。近红外(NIR)光,光谱中介于可见光和红外光之间的一部分,由于其优越的穿透生物组织的能力,作为数据传输的载体非常有利,例如,人体。由于在温度室中干燥会导致肉质量恶化,因此使用猪肉样品作为长时间实验的繁殖介质具有挑战性。通常,可以利用受控温度室将组织样本加热到37°C。有些实验需要长时间进行,在某些情况下超过一个小时,包括传输大型数据的演示(例如,高清图像或视频)使用NIRLED实时通过生物组织。此外,用于统计分析,有些实验需要重复,因此,应避免组织样品的降解。此外,实验还可以包括对在NIR照明下对生物组织进行的光学无线功率传输(OWPT)的调查,并在接收端采用基于能量收集器的商业光伏电池(PV)。这将需要很长时间来为存储充电(例如,电池或超级电容器)完全。使用幻影进行这样的实验也并不简单,需要仔细考虑,比如标准化问题。解决这一挑战的一种可能方法是在自由空间环境中进行实验(例如,无样品),同时保证在自由空间中接收的光功率等于通过生物组织获得的光功率。这可以通过仔细控制LED的电流和布置光学通道的距离来实现,以实现可比较的结果。所接收的光功率是用于比较自由空间和生物组织设置的主要参数。该数据集提供了NIRLED的设置(Pmax=375mW,λ=810nm),允许在自由空间环境中进行体内交流实验。此数据集(自由空间)中的LED电流设置与使用具有5(五)种不同LED电流变化的生物组织的测试床中使用的LED电流设置(即,500mA,400mA,300mA,200mA,和100毫安)。该数据集由六个不同厚度和脂肪肌肉层组成的猪肉样本组成,产生36个数据点。该数据集具有在任何生物医学研究中重复使用的巨大潜力,特别是在利用光的体内通信和能量转移领域。
The utilization of actual biological tissue (e.g., pork meat samples) and tissue-mimicking
phantoms for optical-based in-body data and energy transfer studies is crucial. Near-infrared (NIR) light, a part of the light spectrum that falls between visible light and infrared, is highly advantageous as a carrier for data transmission due to its superior ability to penetrate biological tissue, for instance, the human body. Using pork meat samples as a propagation medium for prolonged experiments is challenging due to the deterioration of meat quality caused by drying in the temperature chamber. Typically, a controlled-temperature chamber can be utilized to warm the tissue samples to 37 °C. Some experiments need to be carried out over long periods, in some cases exceeding one hour, including the demonstration of transmitting large-size data (e.g., high-definition images or videos) in real-time through biological tissue using NIR LED. Moreover, for statistical analysis, some experiments need to be repeated, therefore degradation of the tissue sample should be avoided. Furthermore, experiments may also encompass investigations into optical wireless power transfer (OWPT) conducted on biological tissues under NIR illumination and employing energy harvester-based commercial photovoltaic cells (PV) at the receiving ends, which would require a long time to charge the storage (e.g., battery or supercapacitor) fully. Using
phantoms for such an experiment is also not straightforward, requiring careful consideration, such as standardization issues. One possible approach to address this challenge is to conduct experiments in a free-space environment (e.g., sample-free) while guaranteeing that the optical power received in free-space is equivalent to that obtained through biological tissue. This can be achieved by carefully controlling the LED\'s current and arranging the optical channel\'s distance to achieve comparable results. The received optical power is the primary parameter for comparing free-space and biological tissue setups. This dataset provides settings for NIR LEDs ( P m a x = 375 mW and λ = 810 nm), allowing in-body communication experiments in a free-space environment. The LED\'s current settings in this dataset (free-space) are equivalent in comparison to those used in a test-bed using biological tissue with 5 (five) different variations of LED currents (i.e., 500 mA, 400 mA, 300 mA, 200 mA, and 100 mA). The dataset consists of six pork meat samples with different thicknesses and fat-muscle layer compositions, resulting in 36 data points. This dataset holds significant potential for reuse in any biomedical research, particularly in the fields of in-body communication and energy transfer utilizing light.
