“…Commercial thermopiles commonly use bismuth telluride ( ), having a Seebeck coefficient C, due to the high ZT factor. By using that material for the thermocouple pillars, with a temperature difference C, 5000 thermocouples having a total area of about 25 cm are required to produce a voltage drop 1 V [22]. Moreover, a value of between the thermopile plates is not easily achieved.…”

“…Moreover, a value of between the thermopile plates is not easily achieved. Based on results from [22], placing a commercial thermopile exploiting bismuth telluride (8) a heat flux of about 6 mW flows through the area A. The product of the heat flux by the thermal resistance of the thermopile results in a temperature gradient C, instead of 1 C previously assumed.…”

“…14, each voltage and current of a two-port network can be divided into two components: one incident and the other reflected where the generic element can be expressed as (22) In most of the practical situations, the characteristic impedance is the same for all ports of a network. In that case, its value is indicated as and is called the characteristic impedance of the network.…”

Abstract-This paper reviews some popular techniques to harvest energy for implantable biosensors. For each technique, the advantages and drawbacks are discussed. Emphasis is placed on the inductive links that are able to deliver power wirelessly through the biological tissues and enable bidirectional data communication with the implanted sensors. Finally, high-frequency inductive links are described, focusing also on the power absorbed by the tissues.Index Terms-Energy harvesting, implantable biosensors, inductive powering, remote powering.

“…Seiko was the first company to release a watch powered by the human body heat [13]. Using this strategy, it is also feasible to power wearable sensor nodes, providing about 100 µW when placed on the wrist [17]. A TEG half-buried in the soil can provide up-to 1 W m −2 (peak) to an outdoor sensor node, by exploiting the temperature difference between the buried side and the side exposed to the ambient air [14].…”

Abstract. In this article, the RObject concept is first introduced. This is followed by a survey of applicable energy scavenging technologies. Energy is a key issue for the large scale deployment of robotics in daily life, as recharging the batteries places a considerable burden on the end-user and is a waste of energy which has an overall negative impact on the limited resources of our planet. We show how the energy obtained from light, water flow, and human work, could be promising sources of energy for powering low-duty devices. To assess the feasibility of powering future RObjects with technologies, tests were conducted on commonly available robotic vacuum cleaners. These tests established an upper-bound on the power requirements for RObjects. Finally, based on these results, the feasibility of powering RObjects using scavenged energy is discussed.

“…Soon after that, they were applied, as stated throughout the literature, to many waste heat recoveries. Among these applications, TEGs have been proposed for woodstoves [4]; body heat powered watches [5]; car seat cooling/heating for passenger comfort by the major car manufacturers, including, but not limited to, Toyota, GM, Nissan, Ford and Range Rover [6]; bio-sensors [7]; industrial waste heat recovery to power ancillary devices [8]; vehicular waste heat recovery to enhance fuel economy [9]; and harvesting micropower for low power applications, such as wireless and mobile sensors [10]; just to mention a few. It should be pointed out that currently, TEG applications step beyond the above mentioned areas.…”

New alternatives and inventive renewable energy techniques which encompass both generation and power management solutions are fundamental for meeting remote residential energy supply and demand today, especially if the grid is quasi-inexistent. Solar thermoelectric generators mounted on a dual-axis sun tracker can be a cost-effective alternative to photovoltaics for remote residential household power generation. A complete solar thermoelectric energy harvesting system is presented in this paper for energy delivery to remote residential areas in developing regions. To this end, the entire system was built, modeled, and then validated with the LTspice simulator software via the thermal-to-electrical analogy schemes. Valuable data in conjunction with a novel LTspice circuit were obtained, showing the achievability of analyzing transient heat transfer with the SPICE simulator; however a few of the problems to be solved remain at the practical level. Despite the unusual operation of the thermoelectric modules with the solar radiation, the simulation and measurements were in good agreement, thus validating the new modeling strategy.
