1 Energy Harvesting https://store.theartofservice.com/the-energy-harvesting-toolkit.html

2 Energy harvesting 1 'Energy harvesting' (also known as 'power harvesting' or 'energy scavenging') is the process by which energy is derived from external sources (e.g. solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in Wearable computer|wearable electronics and wireless sensor networks. https://store.theartofservice.com/the-energy-harvesting-toolkit.html

3 Energy harvesting - Operation 1 Another application is in wearable electronics, where energy harvesting devices can power or recharge cellphones, mobile computers, radio communication equipment, etc https://store.theartofservice.com/the-energy-harvesting-toolkit.html

4 Energy harvesting - Accumulating energy 1 The National Science Foundation also supports an Industry/University Cooperative Research Center led by Virginia Tech and The University of Texas at Dallas called the Center for Energy Harvesting Materials and Systems. https://store.theartofservice.com/the-energy-harvesting-toolkit.html

5 Energy harvesting - Accumulating energy 1 Typical power densities available from energy harvesting devices are highly dependent upon the specific application (affecting the generator's size) and the design itself of the harvesting generator https://store.theartofservice.com/the-energy-harvesting-toolkit.html

6 Energy harvesting - Use of the power 1 In these applications an energy harvesting scheme puts power stored into a capacitor then boosted/regulated to a second storage capacitor or battery for the use in the microprocessor.[http://www.linear.com/docs/29710 Energy Harvester Produces Power from Local Environment, Eliminating Batteries in Wireless Sensors] The power is usually used in a sensor application and the data stored or is transmitter|transmitted possibly through a wireless method.[http://www.idtechex.com/research/reports/wireless- power-transmission-for-consumer-electronics-and-electric- vehicles-2012-2022-000281.asp Wireless Power Transmission for Consumer Electronics and Electric Vehicles 2012-2022] https://store.theartofservice.com/the-energy-harvesting-toolkit.html

7 Energy harvesting - Motivation 1 The history of energy harvesting dates back to the windmill and the waterwheel. People have searched for ways to store the energy from heat and vibrations for many decades. One driving force behind the search for new energy harvesting devices is the desire to power sensor networks and mobile devices without batteries. Energy harvesting is also motivated by a desire to address the issue of climate change and global warming. https://store.theartofservice.com/the-energy-harvesting-toolkit.html

8 Energy harvesting - Photovoltaic 1 In recent years new PV technologies have come to the forefront in Energy Harvesting such as Dye Sensitized Solar Cells (Dye- sensitized solar cell|DSSC) https://store.theartofservice.com/the-energy-harvesting-toolkit.html

9 Energy harvesting - Piezoelectric 1 Other industrial applications appeared between 2000 and 2005,[http://www.cedrat.com/en/technologi es/mechatronic-systems/energy- harvesting.html energy harvesting industrial realisations] to harvest energy from vibration and supply sensors for example, or to harvest energy from shock. https://store.theartofservice.com/the-energy-harvesting-toolkit.html

10 Energy harvesting - Piezoelectric 1 These energy harvesting sources by association have an impact on the body https://store.theartofservice.com/the-energy-harvesting-toolkit.html

11 Energy harvesting - Piezoelectric 1 The stretching strain in a doubly clamped beam shows a nonlinear stiffness, which provides a passive feedback and results in amplitude-stiffened Duffing mode resonance.[http://apl.aip.org/resource/1/ap plab/v99/i8/p083105_s1 Ultra-wide bandwidth piezoelectric energy harvesting] https://store.theartofservice.com/the-energy-harvesting-toolkit.html

12 Energy harvesting - Energy from smart roads 1 One way to produce electricity is 'Smart Roads' in which piezoelectric materials such as PZT (Lead Zirconate Titanate) or Micro-electromechanical (MEMS) and PMPG are placed under the layer of roads as they are vibrational energy harvesting devices https://store.theartofservice.com/the-energy-harvesting-toolkit.html

13 Energy harvesting - Pyroelectric 1 However, one key advantage of pyroelectrics over thermoelectrics is that many pyroelectric materials are stable up to 1200 ⁰ C or higher, enabling energy harvesting from high temperature sources and thus increasing thermodynamic efficiency. https://store.theartofservice.com/the-energy-harvesting-toolkit.html

15 Energy harvesting - Blood sugar 1 Another way of energy harvesting is through the oxidation of blood sugars https://store.theartofservice.com/the-energy-harvesting-toolkit.html

16 Energy harvesting - Tree-based 1 Tree metabolic energy harvesting is a type of bio-energy harvesting https://store.theartofservice.com/the-energy-harvesting-toolkit.html

17 Energy harvesting - Biomechanical 1 Body-energy can also be extracted as described for wristwatches (See Energy harvesting#Devices|'devices' above), from Energy harvesting#Blood sugar|blood for pacemakers. https://store.theartofservice.com/the-energy-harvesting-toolkit.html
