Three-Dimensional Photovoltaics Array for Laser-Based Power Transfer

Potential applications include situations in which there is a need to create electrical power at a remote location. Goddard Space Flight Center, Greenbelt, Maryland A standard solar array is a flat panel configured of many individual solar cells, wired in series or parallel, depending on their junction configuration and material. Since the solar flux is constant depending on the distance from the Sun, the maximum energy conversion for a given solar panel depends upon the capability to absorb as many spectral peaks as possible (different materials) across the total solar spectrum. If the radiative source is a man-made device such as a laser, parked in a different orbit or on Earth, then the impinging intensity is narrow spectrally, coherent and accurately pointed, and capable of very high intensities. Thus, the materials can be tailored to match the incoming radiation for maximum absorption.

Nanowire-Based Piezoelectric Power Generation

Energy scavenging is appealing for powering sensors, and for charging cellphones and small consumer electronics. Ames Research Center, Moffett Field, California Sensors have improved in terms of size, capability, and power consumption, but their deployment in remote areas is limited by battery power supplies. Using piezoelectric (PE) materials for energy scavenging is a possible way to remedy the situation. The technology developed in this work converts existing sources of nonpolluting energy (mechanical strain) from nature into electricity. The quantity of energy produced is not massive, but it can be easily generated from free sources such as vibration and electromagnetic waves.

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.
