Current draw by the tag in the transmission scenario at 4.2 V in the supercapacitor. The upper graphic shows the transmission of one datum and the lower graphic the transmission of all data. The numbers represent which element is the one that has the largest contribution to the consumption of the tag in that interval in each case: 1 is for the transceiver, 2 is for the EEPROM and 3 is for the microcontroller. There is a value per number to represent the average consumption of each zone in the two graphics.

In this work, we present autonomous active tags. The power sources of these active tags employ energy harvesting techniques, specifically, solar and mechanical techniques. The integration of these techniques, and the storage of the energy obtained with a supercapacitor, converts the active tag into an autonomous device. These tags work in a low pow...

To ensure maximum comfort for the wearer, electronic components that include energy harvesters need to be mechanically conformable. In this context, we demonstrate a versatile, cost-effective and efficient method for fabricating graphene supercapacitor electrodes using Laser Induced Graphene (LIG). A CO2 laser beam instantly transforms the irradiat...

... These sensors are still difficult to develop due to the power and space limitations, accessibility problems, and the ubiquitous automotive need for reliability. All this points to the use of energy harvesting (EH) and wireless power transfer (WPT) where possible [3]- [6]. Studies already published have highlighted the need to develop methods and strategies to be adopted according to the type of application to be implemented. ...

This paper presents three different techniques for efficiently powering an energy-autonomous wireless sensor (EAWS) through both energy harvesting (EH) and RF wireless power transfer (WPT). The aim of the paper is to provide effective strategies and techniques to reduce, as far as possible, the cost of wiring of the automotive production process due to the continuous and constant increase in the use of sensors. The techniques employ a highly integrated state-of-the-art, ultra-low power 2.5 µW system-on-chip (SoC) system, designed for multi-source RF wireless energy harvesting and power transfer and are designed with the goal of minimizing and, where possible, eliminating the costly maintenance required by conventional wireless sensors. Specific examples are reported that define both the aspects of convenience and the limits of use.
