Wearable sensors have been implemented widely to provide comfortable and continuous long-term monitoring in many applications. Minimal requirements on maintenance is a main characteristic of wearable sensors, but unfortunately, many of them are still powered by battery with limited capacity which need to be charged or replaced regularly. Energy harvesting technologies are applied to provide a reliable solution to this issue. This paper presents several design considerations for self-powered wearable sensors. Suitable energy sources are discussed, such as ambient energy sources (solar, RF, and ultrasonic energy), human body energy (mechanical, piezoelectric, triboelectric, electromagnetic, electrostatic, and thermal energy), and the subcutaneous energy harvesting technique for implantable sensors. Moreover, power management integrated circuits, energy storage options, and the material selection and conditioning circuit of triboelectric nanogenerator (TENG) are discussed. Five case studies utilizing different energy harvesting techniques are discussed and evaluated in terms of their system implementation and performance to provide some deeper understandings of wearable sensors.

Solar energy, the use and importance of which is increasing day by day, stands out among renewable energy sources with many applications. In this study, the application of solar powered orthopedic back support backpack has been presented with a special photovoltaic module structure. The 2x12W photovoltaic panel system has been mounted on the backpack with a rail arrangement and optional use is provided according to the user's preference. Since there will be additional equipment in the solar self-energized backpack compared to a normal bag, the sections where the items should be put in the bag according to their weight should be specified to the user. Considering the center of gravity of the backpack, pockets have been made in the parts where heavy components will be fixed, and a 12V 7Ah lead acid battery is mounted in this section. There is a 5V -1A USB output at the system output and a modified sinus inverter for AC loads. In addition, prototype production was carried out for the realized design, and a backpack was produced, which can be used for charging mobile phones and feeding simple AC loads such as heaters, coolers and shavers. It is thought that this bag will be an attractive product for camping applications and travellers traveling by hitchhiking.

“…In relation to quasi ZSI, there are basically two options for the installation of battery storage to the circuit. This can be seen as proposed in [5]- [11]. However, connecting the battery directly across the capacitor leads to the requirement of designing the battery voltage at a higher value in the series in order to integrate the operating range of the PV terminal and the DC link voltage about the inverter switch.…”

<p>In recent trends, the use of electric vehicles is taking a sudden hike as they seem to be a much more friendly for the environment as compared to the conventional vehicles that run on combustion engines for a mode of transportation. With the increasing popularity of electric vehicles, the demand on the utility grid is also increasing. To overcome this problem, other alternative sources of energy need to be considered. Photovoltaic energy as the solution is finding its place in the EV charging systems. However, the total amount of energy that can be generated from the PV system is constrained, based on many parameters such as solar radiation, availability of space for Solar power plant development, maintenance of the system, etc. Hence, to maintain the continuity of the system, it needs to be integrated with the grid as well. This offers a smooth charging operation for the electric vehicles. In this paper, a new method is introduced for the integration between the solar inverter system and the utility transmission grid. Quasi-Z-source topology is proposed for the system integration. This topology facilitates a bidirectional flow of power between the PV source, the storage unit and the utility grid. The greatest advantage of this topology is its flexibility with different voltage levels of the solar inverter DC connection and the storage battery which requires no circuit alteration for charging batteries of different ratings. The hardware for the system is also fabricated. The results demonstrate that the proposed topology fits the generalized requirements.</p>
