Practical Aspects of Body Communication Systems

人体局域网技术/无线网络利用人体表面作为安全、高速的网络传输路径，它完全不同于无线和红外技术，因为它利用人体表面发射的微小电场。通信可以使用任何表面，例如手、手指、手臂、脚、脸、腿或躯干。这种形式的通信最近由于其安全性和设置和实现方面的简单性而受到关注。这使其成为需要安全数据传输的任何用例的潜在应用（例如，卫生保健部门）。拟议的研究旨在解决阻碍该技术商业化的主要缺点-其准确性和可重复性-因为该技术严重依赖于设计师无法控制的因素。这些因素分为三组：1.受试者相关因素：身高、体重、年龄、性别、皮肤状况、当前情绪、身体姿势、皮肤温度。2.环境相关因素：室温和湿度。3.传感器相关因素：接触电导、电气接地、传感器放置、传感器数量，发射和接收频率。如果不彻底了解这些外部因素的影响，这一领域的技术进步将继续受到限制。谢里丹学院和纳米港技术公司。建议与本研究的目的合作，设计和制造一个身体上的通信系统，并测试一系列外部因素对系统性能的影响。

Human Area Networking technology/Wireless Networking uses the surface of the human body as a safe,high-speed network transmission path. It is completely distinct from wireless and infrared technologies as ituses the minute electric field emitted on the surface of the human body. Communication is possible using anybody surface, such as the hands, fingers, arms, feet, face, legs or torso.This form of communications has recently gained interest due to its secure nature and simplicity in terms of setup and implementation. This makes it a potential application for any use case that requires secure data transfer(e.g., the health care sector). The proposed research aims to solve the main shortcoming deterringcommercialization of this technology - its accuracy and repeatability - as this technology is heavily dependenton factors that are out of the designer's control. These factors are categorized into three groups:1.Subject-related factors: height, weight, age, sex, skin condition, current emotion, body pose, skintemperature.2.Environment-related factors: room temperature and humidity.3.Sensor-related factors: contact conductance, electrical ground, sensor placement, number of sensors,transmission and receiving frequency.The technical progress in this field will continue to be limited without a thorough understanding of the impactof these external factors.Sheridan College and Nanoport Technology Inc. are proposing to collaborate with the aim of this study todesign and fabricate an on-body communications system and test the impact of a series of external factors onthe system performance.
