Energy harvesting gadgets gained momentum with the proposal of triboelectric nanogenerators (TENGs). They can be used to efficiently convert otherwise wasted surface and underwater waves into electricity to power marine-based devices and equipment without greenhouse emissions. In this study, a commercial buoy is modified and a pendulum-like TENG is proposed for ocean wave energy harvesting. Polyurethane (PU) foam and poly(dimethyl siloxane) (PDMS) were utilized as triboelectric couple. From the measurements taken under simulated real case situations in a wave flume, maximum voltage and current values were recorded as 145 V and 8.9 µA, respectively, with a maximum power output of 1.1 W/m2. No performance loss was observed even after 1200 cycles of stability measurement. While presenting the results from the simulated environment, this study highlights and reveals the importance of measurements taken in real situations for understanding the effectiveness of the wave energy harvesters.

Electrostatic energy harvesting by droplet-based multi-phase microfluidics Yıldırım, Ender; Külah, Haluk (2012-07-01) This paper presents an energy scavenging technique, merging microfluidics with electrostatic energy harvesting. The method employs droplet-based microflow of two phases with different electrical permittivities, resulting in a capacitance change across the microchannel, to harvest electrical energy. The technique is implemented on 3 mm wide, 1 mm deep minichannels. It is shown that 0.4 nW can be harvested using a single electrode pair, with air and water as the two phases flowing at 1 ml/min. The generated p...
Biodegradable nanomats produced by electrospinning: Expanding multifunctionality and potential for tissue engineering Ashammakhi, N.; Ndreu, A.; Piras, A. M.; Nikkola, L.; Sindelar, T.; Ylikauppila, H.; Harlin, A.; Gomes, M. E.; Neves, N. M.; Chiellini, E.; Chiellini, F.; Hasırcı, Vasıf Nejat; Redl, H.; Reis, R. L. (2007-03-01) With increasing interest in nanotechnology, development of nanofibers (n-fibers) by using the technique of electrospinning is gaining new momentum. Among important potential applications of n-fiber-based structures, scaffolds for tissue-engineering represent an advancing front. Nanoscaffolds (n-scaffolds) are closer to natural extracellular matrix (ECM) and its nanoscale fibrous structure. Although the technique of electrospinning is relatively old, various improvements have been made in the last decades to...
Tunable Graphene Integrated Perfect Metamaterial Absorber for Energy Harvesting and Visible Light Communication Sabah, Cumali (2018-02-09) Tunable graphene integrated metamaterial absorber is proposed for energy harvesting and visible light communication. The structure provides unity absorption in the visible spectrum in which it can be used perfect absorber for energy harvesting. In addition, it also provides tunability because of the graphene conductivity to be used as photoconductive or thermal switch for visible light communication.
Finite-Horizon Online Transmission Scheduling on an Energy Harvesting Communication Link with a Discrete Set of Rates BACINOĞLU, BARAN TAN; Uysal, Elif (2014-06-01) As energy harvesting communication systems emerge, there is a need for transmission schemes that dynamically adapt to the energy harvesting process. In this paper, after exhibiting a finite-horizon online throughput-maximizing scheduling problem formulation and the structure of its optimal solution within a dynamic programming formulation, a low complexity online scheduling policy is proposed. The policy exploits the existence of thresholds for choosing rate and power levels as a function of stored energy, ...
Analysis of wave gaits for energy efficiency Erden, Mustafa Suphi; Leblebicioğlu, Mehmet Kemal (2007-10-01) In this paper an energy efficiency analysis of wave gaits is performed for a six-legged walking robot. A simulation model of the robot is used to obtain the data demonstrating the energy consumption while walking in different modes and with varying parameters. Based on the analysis of this data some strategies are derived in order to minimize the search effort for determining the parameters of the gaits for an energy efficient walk. Then, similar data is obtained from an actual experimental setup, in which ...
