PiezoElectric Fractal Booster
using fractal math to boost targeted energies Jun 28
A unique international research collaboration is working to develop technologies to help deliver 10 fold increases in chip processor speed, faster internet connections and huge energy savings worldwide. The project, called Nanostrain, brings together public institutions from across Europe supported by global industry leaders, to provide highly accurate measurements of strain in materials at the nano-scale and drive innovation in next generation electronic devices. A particular focus for the consortium is a class of materials (piezoelectrics) that change their shape in response to electric voltages. The project aims to advance commercial opportunities arising from controlled strain in nano-scale piezoelectrics including the development of the first Piezoelectric-Effect-Transistor (PET), a new digital switch with the potential to offer increased speed, reduced micro-chip size and lower power consumption.

Specialized Circuit Drives 150-V Piezoelectric Motor Using Low-Voltage Op Amp | Analog content from Electronic Design A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while a voltage is ramped to warp the piezoelectric material and move the armature. The voltage then is quickly removed. As the material springs back, it breaks away from the armature and returns to its zero position, leaving the armature a few micrometers further along its track. Repeat this at a kilohertz rate and for thousands of times.

Cree`s LED upgrade kit could finish off linear fluorescents June 05, 2013 The firm's new breakthrough technology delivers contractors quick Retrofit to LED lighting Linear fluorescent lighting may have seen its last days thanks to the inventive, new Cree UR Series LED Upgrade Kit. Cree says it can deliver payback in less than two years and makes upgrading to LED lighting simple and easy. Payback has been calculated against a fluorescent three-lamp fixture (with lamp and ballast equal to 88 system watts) and based on typical commercial usage of 12 hours per day and $0.11 per kWh electric costs.
Piezoelectric Keyboard Screen
By Neil Hughes In an effort to make touchscreens less static, Apple has proposed that future iPhones and iPads could feature actuators that would provide haptic feedback to users, and also include sensors that would measure the force at which a user touches the screen. The concept was unveiled this week in a patent application discovered by AppleInsider entitled "Touch-Based User Interface with Haptic Feedback." The use of actuators underneath a touchscreen could allow users to actually feel elements on the screen, such as buttons or controls. The timing of the application being made public by the U.S. Patent and Trademark Office is interesting because one rumor from earlier this month incorrectly suggested Apple would introduce new haptic feedback technology in its third-generation iPad. Apple's haptic touch feedback concept uses actuators, senses force on iPhone, iPad
Boosting LED Efficiency: Zinc Oxide Microwires Improve Performance of Light-Emitting Diodes (LEDs) Through the Piezo-phototronic Effect Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are believed to be the first LEDs whose performance has been enhanced by the creation of an electrical charge in a piezoelectric material using the piezo-phototronic effect. Georgia Tech Regents professor Zhong Lin Wang (right) and graduate research assistant Ying Liu study light-emitting diodes whose performance has been enhanced through the piezo-phototronic effect.

Triboelectric Energy: The Future Of Renewable Power? By EarthTechling's Pete Danko: Where there’s power being produced, there are researchers looking into how it might be harvested and put to use, no matter how small the amount.
MIT Develops an Energy-Harvesting Chip That You Can Shake and Bake ( - Consumer Electronics ) Over the years, we've seen researchers develop some rather unorthodox energy harvesting systems, including photovoltaics (solar panels), piezoelectric materials that react to motion, and thermoelectrics that turn heat into electricity.

The Road - The Trip For Life The world we live in is one where many people have poor eyesight, but surprisingly few can afford corrective lenses so that they can see clearly.
New MIT chip harvests energy from three sources The problem with depending on one source of power in the drive toward the battery-free operation of small biomedical devices, remote sensors and out-of-the-way gauges is that if the source is intermittent, not strong enough or runs out altogether, the device can stop working. A small MIT research team has developed a low-power chip design capable of simultaneously drawing power from photovoltaic, thermoelectric, and piezoelectric energy sources. The design also features novel dual-path architecture that allows it to run from either onboard energy storage or direct from its multiple power sources.

Piezoelectric vs Electrostatic Ultrasonic transducers come in two basic types, piezoelectric and electrostatic. The main difference between the two is that piezoelectric transducers use a ceramic material whereas electrostatic transducers contain a thin metal membrane.

MIT Chip Harvests Energy from Heat, Light and Movement Researchers at MIT have developed a new chip that can continually and almost simultaneously draw energy from three different sources. The chip is designed to harness thermoelectric (heat), photovoltaic (light) and piezoelectric (movement) energy.
