Practical Aspects of Body Communication Systems

城域网络技术/无线网络使用人体表面作为安全、高速的网络传输路径。它与无线和红外线技术完全不同，因为它使用的是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因其安全的性质和在设置和实现方面的简单性而受到关注。这使得它成为任何需要安全数据传输的用例(例如，医疗保健部门)的潜在应用。拟议的研究旨在解决阻碍这项技术商业化的主要缺陷--其准确性和可重复性--因为这项技术严重依赖于设计师无法控制的因素。这些因素被分为三组：1.与受试者有关的因素：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.与环境有关的因素：室温和湿度。3.与传感器有关的因素：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。谢里登学院和Nanoport Technology Inc.提议合作，以实现本研究的目的，设计和制造身体通信系统，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.
