EtherCAT Solution Supercharges IoT-based Smart Factories

The emergence of Cloud-based Internet of Things technologies is redefining industrial automation. Apart from the traditional PLC-based machine automation with low networking capabilities, the new generation IoT based automation enables “smart factory” by connecting all devices to the cloud and combining intelligent software, real time control and monitoring, and big data analysis to optimize product design and production process and ensure quality. The result is higher throughput, lower defection rate and stronger competitiveness based on intelligent automation.

External Power Supply Efficiency Regulation Introduction

Presently Energy Efficiency Level V is mandatory in Canada and throughout Europe. In February 2016 Energy Efficiency Level VI will become mandatory in the United States. Attached are the details of the pending change, but in brief, both the standby power draw and efficiency of the operating power supplies must meet minimum levels set in the standard. MEGA is in the process of updating our product line to comply with the coming changes.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

Public Lighting System Runs on Solar and Wind Energy

A researcher at the Barcelona College of Industrial Engineering, in collaboration with the company Eolgreen, has developed the first autonomous industrialized public lighting system that works with solar and wind energy. This system, developed after four years of research, is designed for inter-urban roads, motorways, urban parks, and other public areas. It is unique in the world, and reduces the cost by 20% compared with conventional public lighting systems. The prototype is 10 meters high and is fitted with a solar panel, a wind turbine, and a battery. The turbine runs at a speed of 10 to 200 rpm and has a maximum output of 400 watts. Work is being done on a second prototype generator that runs at a lower speed (10 to 60 rpm) and has a lower output (100 W). An electronic control system manages the flow of energy among the solar panel, the wind turbine, the battery, and the light. Source:

Zinc Oxide Materials Power Tiny Energy Harvesting Devices

Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable, and powered by ambient renewable energy. This last goal inspired researchers to explore how the attractive physical features of zinc oxide (ZnO) materials could be used to tap into abundant mechanical energy sources to power micro devices. They discovered that inserting aluminum nitride insulating layers into ZnO-based energy harvesting devices led to a significant improvement of the devices’ performance. The group’s findings are expected to provide an effective approach for realizing “nanogenerators” for self-powered electronic systems such as portable communication devices, healthcare monitoring devices, environmental monitoring devices, and implantable medical devices.

Glass as Electrode Makes Batteries More Efficient

Today’s batteries provide a reliable power supply for our smartphones, electric cars and laptops, but are unable to keep up with the growing demands placed on them. Researchers have discovered a material that may have the potential to double battery capacity: vanadate-borate glass. The glass is being used as a cathode material, which is made of vanadium oxide (V2O5) and lithium-borate (LiBO2) precursors, and was coated with reduced graphite oxide (RGO) to enhance the electrode properties of the material. The vanadate-borate glass powder was used for battery cathodes, which were placed in prototypes for coin cell batteries to undergo numerous charge/discharge cycles. In tests, the glass electrodes demonstrated a vast improvement in these batteries’ capacity and energy density. Source:
