An implantable system for monitoring vital parameters via bio-sensors inside freely moving laboratory animals and its powering system are presented. The required 2 mW are harvested by the magnetic coupling with an external coil placed under the living space of the animal. The servo X-Y rails move the external coil and track the animal. Dynamic power-adaptation keeps the harvested power level constant against misalignments of transmitting coil and moving animal. Entire system and basic blocks integrated using a 0.18 um CMOS technology are presented. Experimental results show the effectiveness of the powering system.

“…In order to maximize impedance matching, the input impedance of the rectifier should be determined accurately. Large signal s-parameter (LSSP) simulation permits obtaining the input impedance of a rectifier when it is matched to its source [6]. The simulation uses the the model of a commercially available diode used to build a bridge rectifier (Avago HSMS-2828) as shown in Fig.…”

Far-field remotely powered sensor systems enable long distance operation for low-power sensor systems. In this work, we demonstrate a remote powering platform with a miniaturized antenna and remote powering base station operating at 2.45 GHz. The rectenna, which is the energy receiving and conversion element of the sensor system, is designed and measured. The measurements for the tag are performed within 15 cm distance from the remote powering base station. The realized gain of the tag antenna is measured as -3.3 dB, which is 0.5 dB close to the simulations, where simulated realized gain is -2.8 dB.

“…Implementing efficient WPT and RF EH is not a simple task, because even though RF energy offers high pervasiveness and the ability to be directed to out-of-sight locations, its power conversion efficiency (PCE) remains very low. All this has already prompted many researchers to contribute highly enlightening papers on the subject [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67]. This paper contributes to this field of research with an investigation of RF WPT between a power transmitter (reader) and an RF self-powered, battery-less BLE tag within a WSN infrastructure.…”

Asset tracking involving accurate location and transportation data is highly suited to wireless sensor networks (WSNs) featuring battery-less nodes that can be deployed in virtually any environment and require little or no maintenance. In response to the growing demand for advanced battery-less sensor tag solutions, this article presents a system for identifying and monitoring the speeds of assets in a WSN with battery-less tags that receive all their operating energy through radio frequency (RF) wireless power transfer (WPT) architecture, and a unique measurement approach to generate time-domain speed readouts. The assessment includes performance characteristics and key features of a system on chip (SoC) purposely designed to power a node through RF WPT. The result is an innovative solution for RF to DC conversion able to address the principal difficulties associated with maximum power conversion efficiency (PCE) with sensitivity and vice versa, a strategy, and a design optimization model to indicate the number of readers required for reliable asset identification and speed measurement. Model validation is performed through specific tests. Experimental results demonstrating the viability of the proposed advanced monitoring system are provided.
