A Summary Of Piezoelectric Energy Harvesting For Autonomous Smart Structures


The technology of energy harvesting has great potential to enable energy autonomy of wireless sensors. The drop of power requirements of micro-electronic devices allows confidence that piezoelectric energy harvesting (PEH) is able to reliably power a wireless sensor network (WSN). The present work summarizes results of ongoing research in the field of PEH. With the aid of a performance metric a... » read more

A 10.5 μW Programmable SAR ADC Frontend With SC Preamplifier For Low-Power IoT Sensor Nodes


Massive deployment of wireless autonomous sensor nodes requires their lifetime extension and cost reduction. The analog frontend (AFE) plays a key role in this context. This paper presents a successive approximation register analog-to-digital converter (SAR ADC) with a switched-capacitor programmable gain switched preamplifier (SC PGSA), as a basic component of an integrated ultra-low power AFE... » read more

Blockchain integrated into energy systems Researchers at Canada’s University of Waterloo integrated blockchain technology into energy systems, a development that may expand charging infrastructure for electric vehicles. In a study that outlines the new blockchain-oriented charging system, the researchers found that there is a lack of trust among charging service providers, property owners... » read more

System Bits: July 5


Computer vision for automated data collection Stanford University researchers have developed a computer vision system that automates the collection of data about the elements in buildings in order to streamline the remodeling or refurbishment of existing buildings, which can be fraught with delays and cost overruns due to hidden problems. Renovation projects live and die by the quality of i... » read more
