In our current four years joint project UWB in Medicine we were able to demonstrate the suitability of a carrierless impulse UWB radio for medical sensing applications and wireless sensor node communications in biomedical settings. We developed analog signal processing algorithms, state of the art UWB antennas and a highly flexible impulse UWB chipset for receive and transmit applications. There are still important open points which we want to address in this final 2-years period of UKoLos. This new project proposal UWB in Medicine 2 will now turn its attention to UWB systems which can eventually be placed inside of the human body. Two potential applications, specifically, will guide the research undertaken in the proposed project:• Communication with implants• Localization of interventional devices, such as cathetersSignificant challenges arise, which move beyond the investigations done so far. In the field of circuit design we will demonstrate a further increase in circuit integration with a novel monostatic UWB radar on a single chip. Further, diverging UWB standardization will be addressed using new tunability concepts for low power consumption pulse generators, which are essential for global acceptance of medical UWB, and for patient mobility. The ensemble of methods, circuits, and antennas will be validated in a test bed which addresses the topics of imaging of the body surface, localization and movement-tracking of interventional devices inside the human body, with millimeter-wave accuracy, in the presence of restricted bandwidth, low SNR, multipath propagation and interference.

在我们当前四年的医学 UWB 联合项目中，我们能够展示无载波脉冲 UWB 无线电在生物医学环境中的医疗传感应用和无线传感器节点通信的适用性。我们开发了模拟信号处理算法、最先进的 UWB 天线和技术。用于接收和传输应用的高度灵活的脉冲 UWB 芯片组 在 UKoLos 的最后 2 年期间，我们仍然希望解决一些重要的开放问题，Medicine 2 中的这个新项目提案现在将把注意力转向 UWB 系统。具体来说，两个潜在的应用将指导拟议项目中进行的研究：• 与植入物的通信• 介入设备（例如导管）的定位出现的重大挑战超出了迄今为止所做的研究范围。在电路设计领域，我们将展示单芯片上新型单基地 UWB 雷达的电路集成度的提高。此外，将使用新的低功耗脉冲发生器可调谐概念来解决不同的 UWB 标准化问题，这对于全球而言至关重要。医疗 UWB 的接受以及患者移动性的方法、电路和天线的整体将在测试台中进行验证，该测试台涉及人体表面成像、人体内介入设备的定位和运动跟踪等主题，在带宽受限、信噪比低、多径传播和干扰存在的情况下，具有毫米波精度。
