Harvesting biomechanical energy in the walking by shoe based on liquid metal magnetohydrodynamics

Dan DAI, Jing LIU, Yixin ZHOU

Frontiers in Energy 2012, Volume 6, Issue 2,   Pages 112-121 doi: 10.1007/s11708-012-0186-x

Abstract: A liquid metal magnetohydrodynamics generation system (LMMGS) was proposed and demonstrated in this paper for collecting parasitic power in shoe while walking. Unlike the conventional shoe-mounted human power harvesters that use solid coil and gear mechanism, the proposed system employs liquid metal (Ga In Sn ) as energy carrier, where no moving part is requested in magnetohydrodynamics generators (MHGs). While walking with the LMMGS, the foot alternately presses the two liquid metal pumps (LMPs) which are respectively placed in the front and rear of the sole. As a result, the liquid metal in the LMPs (LMP I and II) is extruded and flows through the MHGs (MHG I and II) in which electricity is produced. For a comparison, three types of LMMGSs (LMMGS A, B and C) were built where all the parts are the same except for the LMPs. Furthermore, performances of these LMMGSs with different volume of injected liquid metal were tested respectively. Experimental results reveal that both the output voltage and power of the LMMGS increase with the volume of injected liquid metal and the size of the LMPs. In addition, a maximum output power of 80 mW is obtained by the LMMGS C with an efficiency of approximately 1.3%. Given its advantages of no side effect, light weight, small size and reliability, The LMMGS is well-suited for powering the wearable and implantable micro/nano device, such as wearable sensors, drug pumps and so on.

Simultaneous harvesting and cell disruption of microalgae using ozone bubbles: optimization and characterization

Wan N. A. Kadir, Man K. Lam, Yoshimitsu Uemura, Jun W. Lim, Peck L. Kiew, Steven Lim, Siti S. Rosli, Chung Y. Wong, Pau L. Show, Keat T. Lee

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 5,   Pages 1257-1268 doi: 10.1007/s11705-020-2015-9

Abstract: In the present study, ozone was introduced as an alternative approach to harvest and disrupt microalgae cells ( ) simultaneously for biodiesel production. At the optimum ozonation conditions (6.14 g·h ozone concentration, 30 min ozonation time, 1 L·min of ozone flowrate at medium pH of 10 and temperature of 30 °C), the sedimentation efficiency of microalgae cells increased significantly from 12.56% to 68.62%. It was observed that the microalgae cells aggregated to form flocs after pre-treated with ozone due to the increment of surface charge from –20 to –6.59 mV. Besides, ozone had successfully disrupted the microalgae cells and resulted in efficient lipid extraction, which was 1.9 times higher than the control sample. The extracted microalgae lipid was mainly consisted of methyl palmitate (C16:0), methyl oleate (C18:1) and methyl linolenate (C18:3), making it suitable for biodiesel production. Finally, utilization of recycled culture media after ozonation pre-treatment showed robust growth of microalgae, in which the biomass yield was maintained in the range of 0.796 to 0.879 g·h for 5 cycles of cultivation.

Hip-mounted electromagnetic generator to harvest energy from human motion

Dan DAI,Jing LIU

Frontiers in Energy 2014, Volume 8, Issue 2,   Pages 173-181 doi: 10.1007/s11708-014-0301-2

Abstract: A type of electromagnetic hip-mounted generator (EHG) is proposed to harvest energy from human hip motion to generate electricity. Based on the law of electromagnetic induction, the EHG generator can convert the kinetic power of the thigh swing into electrical energy during walking or running. To demonstrate the feasibility of the present method, a prototype of the EHG has been designed and fabricated. A theoretical analysis has been conducted to interpret the working behavior of this prototype. In addition, the performance of the system has been experimentally tested through a rotary motor and human body motion. When driven by the rotary motor at a rotation speed of 100 r/min, the open-circuit voltage of this prototype is 2.5 V. Further, a maximum open-circuit voltage of approximately 1 V and a maximum output power of 284 μW could be produced respectively when walking with an EHG at a speed of 1.47 m/s. This handy renewable energy technology is promising as a pervasive electricity generation system for a group of wearable or implanted sensors, actuators and mobile electronics.

Joint cooperative beamforming and artificial noise design for secureAF relay networks with energy-harvesting Article

He-hao NIU, Bang-ning ZHANG, Dao-xing GUO, Yu-zhen HUANG, Ming-yue LU

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 6,   Pages 850-862 doi: 10.1631/FITEE.1601832

Abstract: In this paper, we investigate physical layer security for simultaneous wireless information and power transfer in amplify-and-forward relay networks. We propose a joint robust cooperative beamforming and artificial noise scheme for secure communication and efficient wireless energy transfer. Specifically, by treating the energy receiver as a potential eavesdropper and assuming that only imperfect channel state information can be obtained, we formulate an optimization problem to maximize the worst-case secrecy rate between the source and the legitimate information receiver under both the power constraint at the relays and the wireless power harvest constraint at the energy receiver. Since such a problem is non-convex and hard to tackle, we propose a two-level optimization approach which involves a one-dimensional search and semidefinite relaxation. Simulation results show that the proposed robust scheme achieves better worst-case secrecy rate performance than other schemes.
