“…VER THE past two decades, we witnessed the revolution of wireless sensor network (WSN) and the associated fields, including, Internet of Things (IoT), wearable and implantable biomonitoring devices, machine to machine communication and cyber-physical systems [1]- [3]. One of the visions of WSN is to autonomously monitor the environmental parameters such as temperature, moisture, and dissolved oxygen [4], [5].…”

“…However, these rectifiers suffer from poor low-power performance and poor PCE due to the high dropout voltage across the diodes [35]. Non-CMOS technologies such as Schottky diodes can enhance the low-power performance of the diode-based rectifiers [3], [36]. However, it is seldom offered in conventional CMOS processes; hence, it cannot be used in lowcost applications where high integration level is needed [3], [35].…”

“…Lowering the threshold voltage of the FX architecture shifts the efficient operating region toward the lower input power range by sacrificing the high-power PCE performance. To this end, Schottky diode-based architectures perform better at very low input power due to their low threshold voltage [3], [18], [41], and there is a need to reduce the effective threshold voltage of the CMOS-based architectures without sacrificing the PCE at high input power.…”

This paper proposes a dual-mode nested RF rectifier for ambient wireless powering. The proposed architecture utilizes a dual-mode nested feedback circuit to enhance the conductivity of the rectifier at low-power while reducing the reverse leakage current at high-power by generating supply voltages at the gates of the PMOS rectifying transistors. The proposed rectifier is fabricated in 65 nm CMOS technology and occupies an area of 6480 µm 2. The measurement results show a peak power conversion efficiency of 86%, 10.1 dB dynamic range, and-19.2 dBm 1-V sensitivity when operating with a 100 kΩ load at the industrial, scientific and medical band 433 MHz. Moreover, the enhanced low-power performance is achieved by reducing the effective threshold voltage of the rectifier by about 37%, compared to a lowthreshold transistor in 65 nm technology. This reduction in the threshold voltage allows the rectifier to operate with efficiency exceeding 10% for input power ≥-40 dBm.

“…In common working conditions [25], a substantial reduction in battery power consumption can be achieved by reducing or eliminating standby power [26][27][28][29][30][31][32][33][34], which can directly translate into longer system lifetime, further miniaturization, and reduced maintenance intervention frequencies. Maintenance of battery-powered nodes can also be facilitated by implementing over-the-distance wireless battery charging using radio frequency (RF) wireless power transfer (WPT) [35][36][37][38][39][40]. While these solutions can help alleviate maintenance and miniaturization problems, they cannot solve them altogether.…”

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.

We realize a vibration energy harvesting system based on fully printed piezoelectric transducers. The transducers have a butterfly‐like architecture based on two single optimized cantilevers with a resonance frequency tuned to 49.5 Hz and can be easily mounted to an industrial engine. By comparing single and multi‐stack configurations of the piezoelectric layers combined with full‐wave or voltage doubler rectifiers, the power transfer characteristics and impedance can be matched to the electrical requirements of the sensing circuitry. A single stack with 21 µm thickness results in the maximum power output of 14.4 µW at a vibration velocity of 11.5 mms‐1, typical for industrial engines. We use the system to power a wireless sensor node on a 1 kW rotary pump in normal operation. The system can harvest up to 138 mJ within 24 hours, sufficient for daily remote monitoring of the engine’s vibration spectrum and temperature state. Our system is thus suitable as low‐cost, ecofriendly power source for industrial IoT applications.This article is protected by copyright. All rights reserved.
