Description This is a 1×1 inch PCB module with two tiny solar cells, a highly efficient Li-Ion battery charger and with two regulated outputs (3.3V and 1.8V). It harvests enough power from indoor light to power a simple BLE or LoRa sensor. The board has castellated vias so it can be surface mount soldered onto […]

A group of Researchers from Purdue University in Lafayette, Indiana demonstrated the effect called negative capacitance by making a new type of more energy efficient transistor. This new kind of Field Effect Transistor (FET) proves a theory introduced in 2008 by Supriyo Datta, the Thomas Duncan Distinguished Professor of Electrical and Computer Engineering, and Sayeef Salahuddin, who is a professor of Electrical Engineering and

In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will now use two case studies to illustrate these properties in detail. Case Study 1: Using a small solar cell indoors at low light, 100 lux,

Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If the material can be scaled up from laboratory samples, devices made

The latest buzz in the information technology industry regards “the Internet of things”—the idea that vehicles, appliances, civil-engineering structures, manufacturing equipment, and even livestock would have their own embedded sensors that report information directly to networked servers, aiding with maintenance and the coordination of tasks. Realizing that vision, however, will require extremely low-power sensors that

Stephen Evanczuk writes: Lithium-ion batteries have emerged as a common energy-storage device in many energy-harvesting applications. For engineers, maximizing battery performance and lifecycle requires use of battery charging circuitry able to account for the specialized characteristics of Li-ion cells

(PRWEB) June 08, 2011 A distinguishing feature of offshore wind turbine structures is that the turbines impose a large horizontal load, at a great height, above the turbines foundation. The over-turning forces at foundation level resulting from this high ratio of lateral-to-vertical loading implies a loading regime that is very different from that of existing

London (PRWEB) July 14, 2011 Unless an offshore wind farm is optimally designed, even the most powerful offshore wind turbine will under-perform. While there will always be a trade-off between turbine performance losses and wind farm lay-out cost savings, the trick is knowing how to strike the right balance, says Wind Energy Updates 2011 Offshore
