Abstract:The fabrication and characterization of a thermoelectric energy harvester using the complementary metal oxide semiconductor (CMOS)-microelectromechanical system (MEMS) technology were presented. The thermoelectric energy harvester is composed of eight circular energy harvesting cells, and each cell consists of 25 thermocouples in series. The thermocouples are made of p-type and n-type polysilicons. The output power of the energy harvester relies on the number of the thermocouples. In order to enhance the output power, the energy harvester increases the thermocouple number per area. The energy harvester requires a post-CMOS process to etch the sacrificial silicon dioxide layer and the silicon substrate to release the suspended structures of hot part. The experimental results show that the energy harvester has an output voltage per area of 0.178 mV¨mm´2¨K´1 and a power factor of 1.47ˆ10´3 pW¨mm´2¨K´2.

“…All these requirements have a direct impact on the key performance figures for low-power receivers. Communication range and channel characteristics directly influence the necessary To make the system autonomous, the power supply for the nodes is provided by an energy harvester [3] in combination with a power management board [4]. Such an energy harvester can provide up to 23J per flight.…”

In wireless sensor networks (Wsns) energy efficiency and communication reliability are often conflicting requirements. additionally, some application areas such as industrial automation or infrastructure monitoring impose strict latency bounds.Low-power receivers ( mW 1 1 power consumption) together with adapted mac protocols have the potential to meet these diverse requirements. We present an overview of state-of-the-art low-power receivers and relate their characteristics to requirements for different application areas. We compare low-power receivers to duty-cycled transceivers and present applications depending on them. For this, we use power consumption, sensitivity, and data rate as key performance figures for low-power receivers. Based on the characteristics of the applications we derive guidelines for using low-power receivers instead of duty-cycled transceivers. project "AETERNITAS".Johannes Blanckenstein works on communication protocols in the general field of wireless sensor networks and especially on protocols and applications for low-power wake-up receivers. He writes his doctoral thesis at University Paderborn in the computer networks group of Holger Karl. At the same time he works at Airbus Group Innovations in the field of WSN applications for aeronautics.

“…8,9 However, while the energy output exceeds the requirements of state-of-the-art sensor nodes for appropriate device sizes, applicability has been limited to flight scenarios involving temperature profiles crossing 0 C, because the PCM used was water. In this paper, we use a device of the type presented in Ref.…”

“…The corresponding properties of water are also shown for comparison with previously reported devices. 9,10 In all experiments, the amount of PCM used was 23 ml, which is 7 ml less than the container capacity in order to accommodate phase change expansion.…”

Heat storage energy harvesting devices have promise as independent power sources for wireless aircraft sensors. These generate energy from the temperature variation in time during flight. Previously reported devices use the phase change of water for heat storage, hence restricting applicability to instances with ground temperature above 0 °C. Here, we examine the use of alternative phase change materials (PCMs). A recently introduced numerical model is extended to include phase change inhomogeneity, and a PCM characterization method is proposed. A prototype device is presented, and two cases with phase changes at approximately −9.5 °C and +9.5 °C are studied.
