This Small Business Innovation Research Phase II project proposes to integrate a new, free-space electric field (E) sensor with a recently introduced, miniaturized magnetic induction (B) sensor to form a compact six-channel sensor system. The proposed new E-field + B-field sensor should offer a completely new instrumentation capability for geosciences, providing for the first time measurement of all components of the electromagnetic (EM) field vector at low frequency in a single package without contact to the ground or any other physical object. The Phase II objectives are to develop a system prototype with sensitivity and bandwidth suitable for the majority of applications in geophysical surveying, lightning detection, electromagnetic sounding for detection of buried objects, and for general EM research. A side-by-side comparison with state-of-the-art conventional technology will be performed for magneto-tellurics and lightning detection in collaboration with academic and industry experts.This technology should help develop products for the stand-alone electric and magnetic sensors, as well as a new class of bio-electrode that shares the same basic technology as the E-field sensor. Applications for the bio-electrodes are for human physiologic monitoring such as the electrocardiogram (ECG) and the electroencephalogram (EEG

该小型企业创新研究第二阶段项目建议将新的自由空间电场（E）传感器与最近推出的小型化磁感应（B）传感器集成，以形成紧凑的六通道传感器系统。拟议的新的E场+B场传感器应该为地球科学提供一种全新的仪器能力，首次在单个封装中以低频测量电磁（EM）场矢量的所有分量，而不接触地面或任何其他物理对象。第二阶段的目标是开发一个系统原型，其灵敏度和带宽适用于地球物理测量、闪电探测、用于探测地下物体的电磁测深和一般EM研究中的大多数应用。将与学术界和行业专家合作，对大地电磁学和闪电探测的最新传统技术进行并排比较。这项技术将有助于开发独立的电磁传感器产品，以及与电场传感器共享相同基本技术的新型生物电极。生物电极的应用是用于人体生理监测，例如心电图（ECG）和脑电图（EEG
