Abstract

Healthcare of the future will rely on lots of sensor devices especially long term monitoring sensors. In order to gain acceptance by the patients these devices have to be completely imperceptible and maintenance free. A solution to these requirements is a remote powered implantable sensor system. One of the biggest challenges of such systems is the power supply. Ideal sensor systems do not require any kind of battery for reliable operation. Instead they harvest the energy from the electromagnetic field of the interrogating device. In this talk a possible solution to this problem will be presented. The sensor system is based on an integrated circuit, which consists of a backscattering transceiver and an ultra-low-power analog-to-digital converter (ADC) for sensor data acquisition. With its power consumption of less than 10 μ\ν incl. the ADC, it is possible to harvest the energy from the electromagnetic field and supply the complete ASIC.

远程供电医疗植入物

未来的医疗保健将依赖于大量的传感器设备，特别是长期监测传感器。为了获得患者的接受，这些装置必须是完全难以察觉和免维护的。一个解决这些需求的方案是远程供电植入式传感器系统。这种系统最大的挑战之一是电力供应。理想的传感器系统不需要任何类型的电池来可靠运行。相反，他们从审讯装置的电磁场中获取能量。在这次演讲中，我们将提出这个问题的一个可能的解决方案。该传感器系统基于集成电路，由后向散射收发器和用于传感器数据采集的超低功耗模数转换器(ADC)组成。它的功耗小于10 μ ν(包括ADC)，可以从电磁场中收集能量并提供完整的ASIC。
