Abstract

Wearable wireless sensors are nowadays intensively investigated for continuous monitoring of biomedical parameters and are expected to be pervasively distributed on-body in the next future. In this work, a simulation model for the prediction of the Specific Absorption Rate (SAR) and the temperature variations of keratinocytes in vitro and epidermis in vivo is developed as a preliminary tool for predicting exposure effects of these wearable electronics. Skin cells in a culture medium and in a multi-layered tissue model consisting of epidermis, fat and muscle, have been exposed to electromagnetic (EM) fields generated by patch antennas at 1.8, 2.4 and 60 GHz, that are the most probable frequency bands that will be exploited for wearable applications, accounting for the dispersive models of the different tissues.
特定吸收率和热变化对暴露于射频的角质形成细胞和表皮的模拟影响
可穿戴无线传感器在生物医学参数的连续监测方面得到了广泛的研究,并有望在未来广泛应用于人体。在这项工作中,开发了一个预测体外和体内表皮角质形成细胞的比吸收率(SAR)和温度变化的模拟模型,作为预测这些可穿戴电子产品暴露效应的初步工具。培养基中的皮肤细胞和由表皮、脂肪和肌肉组成的多层组织模型中,暴露于1.8、2.4和60 GHz贴片天线产生的电磁场(EM)中,这是最可能用于可穿戴应用的频段,考虑到不同组织的色散模型。
