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.

这项小型企业创新研究（SBIR）I期项目的更广泛的影响/商业潜力是使低能，低功率，身体安全的身体区域网络（BAN）开放应用程序和用例。禁令是可穿戴计算设备的无线网络。典型的禁令装置嵌入体内，因为撞击，在固定位置表面安装在人体上，或掺入人类携带的参与设备中。当今的标准禁令技术依赖于电子波来进行禁令通信，与禁令节点中的传感和计算相比，它在物理上并没有更大的功率，这使得通信将能量瓶颈用于超低功率禁令设备。该项目将导致一类新的设备，这些设备将人体用作“电线”，以达到比当今人体的通信低的数量级功率，同时使用电子准静态静态人体传播技术可以在物理上固定。这项技术将使无电池禁令操作成为可能，并启用诸如远程物理健康监控，运动员性能监控，安全访问控制，神经监测以及未来可能的脑机界面的应用程序。这项小型企业创新研究（SBIR）I阶段项目旨在通过利用人体作为安全的交流媒介来设计演示可穿戴的乐队。该频段利用电Quasi静态人体通信（EQS-HBC）来证明体内设备之间的无缝通信，并主要包含体内的信号泄漏。预计Body-Wire原型可以通过减少100倍的能量来解决电池寿命的问题，从而允许更长，更智能，较小（新的形式因素）设备。减少能量和改善的物理安全性（除了加密之外）可能会为许多具有新形式的新传感器节点（例如连接的贴片）打开可能性。关于人体姿势的影响，周围环境，人间变异对整体特征的影响，人体作为通信渠道的安全性将从电路设计的角度从巡回设计的角度来理解必要的设计规范，并使无电池，物理传感器节点等应用实用。这种奖项反映了NSF的法定任务，并通过评估了构成的范围，以构成诚实的范围。
