A team of former ETH students from Zurich, Switzerland, developed a water generator system, which can be installed between hose connectors to help reducing waisting one of the most important resources on this planet by tracking your shower habits. Hot water usage for showers is a major source of energy consumption in households. Energy on Demand   The Amphiro a1 comes to live on as soon as you turn on your shower and provides real-time information on a large, easy to read display. Durin ...
The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body. The heart of the sensor is a vibrating cantilever, a thin beam attached at one end like a miniature diving board. Music within a certain range of frequencies causes the cantilever to vibrate, generating electricity and storing a charge in a capacitor, said Babak Ziaie, a Purdue University professor of electrical and computer engineering and biomedical engi ...

  The cost for energy is steadily increasing and at the same time the urge for "free" energy is getting more important. Energy harvesting is one solution to gain "free" energy from sources in your environment. The Wurth Elektronik Energy Harvesting to Go Design Kit allows you to gain energy by temperature, vibration, light and magnetic energy. It already has build in transducers in form of a solar module and a peltier element. Other connectable sources could be a piezo or an inductive elem ...

Energy Harvesting in the age of an "Internet of Things"       Segments of our cities are being infused with technology capable of scavenging energy from the environment, and then using that harnessed power to drive low power communication and sensor technologies. Traffic patterns, pollution monitoring, parking space availability, and utility usage will soon become accessible to citizens in real-time with the combination of embedded sensors and wireless communication being distrib ...

most powerful millimeter-scale energy harvester     Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. And it's smaller than a penny.   This new vibration energy harvester is specifically designed to turn the cyclic motions of factory machines into energy to power wireless sensor networks. These sensor netw ...
ZigBee Wireless Adopts Energy HarvestingZigBee low-energy radios can work without batteries     The low-power wireless energy “Internet of Things” standard ZigBee, used in smart metering systems, is now available in a battery-free version which harvests energy. The new specification will allow ZigBee, which is specified within the UK government’s ambitious smart meter programme, to operate without batteries by harvesting energy such as ambient radio waves.   ...

Virus-powered smartphones US scientists developed a piezoelectrical generator made of viruses. Electricity is generated by pressing the virus. Embedded into your shoe sole, this could create current for mobile devices while walking.   Charged proteins The generator creates current on the base of the piezoelectrical effect: Mechanical energy such as pressure is transformed into electrical energy. Scientists discovered that the M13-Virus is piezoelectric, caused by 2.700 charged proteins c ...
Piezo, Solar and Peltier Scientists at the Massachusetts Institute of Technology (MIT) developed an energy harvesting generator using piezo, solar and peltier energy. Their system supplies sensors with the energy from all 3 sources.   3 Sources - the generator transforms vibration, sunlight and heat into electrical energy. The advantage is to power one single sensor with more than one source. But there is a big difference within the efficiencies of each source: peltier systems reach betw ...
Transparent generator generates electricity through friction A simple generator consisting of 2 synthetic layers - polyester and polydimethylsiloxane - transforms mechanical energy into electrical energy. When both materials are rubbed against each other, the polyester releases electrons which can be absorbed by the polydimethylsiloxane. After this is done both surfaces get separated again. As the process repeats alternating current is produced.   To increase the efficiency of the generat ...
Electricity from a tea light T-Pod is a small power plant for on the road. Powered by a small candle, the device can generate electricity for lamps or can charge cell phone batteries. Tea lights are normally used to keep things warmed up. This generator turns a candle into an energy source.   Thermoelectric Effect The device is called Thermoelectric Power On Demand 1 (T-Pod 1), it transforms thermoelectric heat into electric current. A candle heats the material which generates electricity ...
Biomechanical energy harvesting from human motion offers a promising clean alternative to electrical power supplied by batteries for mobile electronic devices.   Energy harvesting is the use of ambient energy to provide electricity for small and mobile equipment, whether electrical or electronic. Four main ambient energy sources are present in our environment: mechanical energy (vibrations, deformations), thermal energy (temperature gradients or variations), radiant energy (sun, infrared, ...

Energy Harvesting - Peltier

Thermal Energy Harvesting: MSX Technology and Micropelt GmbH   Most domestic appliances carry an energy label indicating their efficiency in using electrical energy. Hobs for electric or gas based cooking do not receive such labels because their efficiency was found not to vary much across the market. New technologies for energy-saving cooking are expected to be part of a new EU directive, introducing an energy label for all hobs, because they are considered a major energy savings potentia ...
