The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to enable low energy, low power, physically secure Body Area Network (BAN) opening applications and use cases. BANs are wireless networks of wearable computing devices. Typical BAN devices are embedded inside the body as implants, surface-mounted on the body in a fixed position, or incorporated into accompanying devices which humans carry. Today's standard BAN technologies rely on electromagnetic waves for BAN communication, which is not physically secure and consume orders of magnitude more power compared to sensing and computation in a BAN node, making the communication link the energy bottleneck for ultra-low-power BAN devices. This project will lead to a fundamentally new class of devices that use the human body as a "wire" to achieve orders of magnitude lower power than today’s communication around the human body while simultaneously being physically secure using Electro Quasi-Static Human Body Communication technology. This technology will make battery-less BAN operation possible and enable applications like remote physiological health monitoring, athlete performance monitoring, secure access control, neural monitoring, and possibly brain-machine interfaces in the future. This Small Business Innovation Research (SBIR) Phase I project seeks to design a demo wearable band by utilizing the human body as a secure communication medium. The band utilizes Electro-Quasi-Static-Human Body Communication (EQS-HBC) to demonstrate seamless communication between devices around the body with signal leakage primarily contained within the body. The body-wire prototype is expected to solve the problem of increased battery life by achieving a 100x reduction in energy, allowing longer-lasting, smarter, smaller (new form-factors) devices. The energy reduction and improved physical security (in addition to encryption) may open possibilities for many new sensor nodes with new form factors (e.g., connected patch). The studies about the effect of human body postures, surrounding environment, inter-human variation on the overall characteristics, and security of the human body as a communication channel will provide an understanding of the necessary design specifications from a circuit design perspective and make applications like battery-less, physiological sensor nodes practical.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业创新研究 (SBIR) 第一阶段项目的更广泛影响/商业潜力是实现低能耗、低功耗、物理安全的人体局域网 (BAN)，开放应用和用例是可穿戴计算设备的无线网络。典型的 BAN 设备作为植入物嵌入体内，安装在身体表面的固定位置，或者合并到人类携带的随附设备中。当今的标准 BAN 技术依赖于电磁波进行 BAN 通信，这在物理上并不安全。与 BAN 节点中的传感和计算相比，其功耗要高出几个数量级，从而使通信链路成为超低功耗 BAN 设备的能源瓶颈。该项目将催生一种以人体作为传感器的全新设备。一种“电线”，可实现比当今人体通信低几个数量级的功率，同时使用电准静态人体通信技术实现物理安全。该技术将使无电池 BAN 操作成为可能，并支持远程生理健康等应用。监控、运动员表现监控、安全访问该小型企业创新研究 (SBIR) 第一阶段项目旨在利用人体作为安全通信媒介来设计一款演示可穿戴手环。 -静态人体通信（EQS-HBC），用于演示身体周围设备之间的无缝通信，信号泄漏主要包含在体内。人体线原型有望通过实现 100 倍的减少来解决延长电池寿命的问题。能量，允许更持久、更智能、更小（新外形）的设备，能源的减少和物理安全性的提高（除了加密之外）可能会为许多具有新外形（例如连接贴片）的新传感器节点带来可能性。人体姿势、周围环境、人与人之间的差异对整体特性的影响以及人体作为通信通道的安全性，将从电路设计的角度理解必要的设计规范，并实现无电池等应用，生理传感器节点实用化。本次获奖体现通过使用基金会的智力价值和更广泛的影响审查标准进行评估，NSF 的法定使命被认为值得支持。
