Authors: Kiziroglou M E , Wright S W , Shi M , Boyle D E , Becker Th , Evans J W , Yeatman E M 
Published: December 2019

Abstract
In this work we demonstrate a power supply that collects thermal energy from temperature fluctuations in time, to provide regulated power in the milliwatt range. It is based on the dynamic thermoelectric energy harvesting concept, in which a phase change material is used to store heat and create spatial heat flow from temperature transients. A simple, cost-effective and reproducible fabrication method is employed, based on 3D printing and off-the-shelf components. The harvester is integrated with a commercial power management module and supercapacitor storage. Output energy up to 2 J is demonstrated from temperature cycles corresponding to avionic applications. The demonstration includes harvesting while powering a 10 kΩ analogue voltmeter directly from the supercapacitor, including during cold-starting.

Published: December 2019

Abstract
The urgent demand for portable electronics has promoted the development of high-efficient energy sources. A typical portable device requires a low power input that can be supplied by a supercapacitor (SC), which are high-power energy-storage devices enabled by reversible ion adsorption at electrolyte/electrode interface with superior properties such as long cycling life and high-power. However, current SCs using aqueous electrolytes possess the safety hazard of liquid leakage meanwhile solid polymer electrolytes can address this issue, and offers advantages such as simple assembly, low cost and flexible packages, and possible high-voltage operation. In this paper we report a flexible SPEEK supercapacitor used simultaneously as solid-state electrolyte, and ion-conducting surfactant.
Demonstration of an electret generator using self-assembled electret for energy harvesting without any charging process
Authors: Matsuura N , Ishii H , Tanaka Y 
Published: December 2019

Abstract
Electret generators (EGs) for energy harvesting is a device which ambient vibrations convert into electric energy. They are expected as power supplies for low energy applications such as wireless sensors. In EGs, charges are induced by an electric field of electret, and thus output power is determined by a surface charge density (σ) of the electret. Various charging processes were proposed so far to realize the electret with high σ, however, they were one of problems decreasing productivity. The elimination of the processes is extremely desired. In this study, we developed charged film composed of 1,3,5-tris(1-phenyl-1H-benzimidazol-2-yl) benzene (TPBi) without any charging process. A surface potential (SP) exceeded 46 V for ca. 740 nm thick film due to spontaneous orientation of TPBi, and was sufficiently stable under room light illumination in atmosphere. Finally, we demonstrated EGs utilizing TPBi as electret generated an AC current of the order of nano-ampere in environmental condition, indicating the feasibility of EGs using TPBi film in practical atmosphere. The series of results strongly suggested that application of spontaneous orientation of polar molecules was promising for the realization of EGs with high productivity.

Polymer-Based Piezoelectric Energy Harvester for Low-Frequency Vibration Using Frequency Up-Conversion Driven by Collision with a Flexible Beam
Authors: Tsukamoto T , Umino Y , Hashikura K , Shiomi S , Yamada K , Suzuki T 
Published: December 2019

Abstract
This paper reports a polymer-based piezoelectric vibration energy harvester using mechanical frequency up-conversion driven by collision with a flexible beam, targeting for low-frequency vibration (under 10 Hz). By driving the flexible beam with low-frequency, the beam periodically hits against the underlying impact-driven piezoelectric component and excites the free oscillation, i.e. frequency up-conversion. We verified the validity of the proposed method by FEM analysis and the proposed vibration energy harvester showed 32 μW at 9 Hz of excitation frequency.

Usefulness and Performance Comparison of Complex Enzyme-type Biofuel Cell Using Electrode Modified with Two DET-type Enzymes by Covalent Bonding
Authors: Fujita H. , Nishioka Y. , Imai S. 
Published: December 2019

Abstract
The demand for enzymatic biofuel cells (EBFCs) as power sources or auxiliary power sources for small devices is expected to increase in the near future. EBFCs have advanced properties and do not require a separator, depending on the substrate specificity of the enzyme. Two direct electron transfer (DET)-type enzymes were used to modify anodes (length 5 mm, width 4 mm) by a chemical modification method using a condensation agent. The DET-type enzymes used in this study were pyrroloquinoline quinone-dependent glucose dehydrogenase (PQQ-GDH) with glucose as a reaction substrate and fructose dehydrogenase (FDH) using fructose as a reaction substrate. Carboxyl groups were attached to multi-walled carbon nanotubes (MWCNTs) that act as catalyst carriers, activated to other functional groups, and reacted with the amino groups of the enzyme by the condensation agent to form covalent bonds. As a result, the upper limit of the concentration, considered to be the reaction limit, was raised as compared with that of EBFC modified with only one kind of enzyme for each electrode prepared by the same process. The output voltage was 0.155 V, and the maximum power density was 80.08 μW/cm2. Also the deterioration characteristics were confirmed with the passage of time for EBFC-Z; the maximum power density was almost unchanged for three months, and output reduction due to the passage of time was not observed.

Published: December 2019

Abstract
In the last decades, many research groups have experimented the synthesis of hydroxyapatite (HA) for bone tissue application obtaining products with different shapes and dimensions. This review aims to summarise and critically analyse the most used methods to prepare physiologic-like nano-HA, in the form of plates or rods, similar to the HA present in the human bones. Moreover, mesoporous HA has gained increasing interest in the biomedical field due its pecualiar structural features, such as high surface area and accessible mesoporous volume, which is known to confer enhanced biological behaviour and the possibility to act as nanocarriers of functional agents for bone-related therapies. For this reason, more recent studies related to the synthesis of mesoporous HA, with physiological-like morphology, are also considered in this review. Since a wide class of surfactant molecules plays an essential role both in the shape and size control of HA crystals and in the formation of mesoporosity, a section devoted to the mechanisms of action of several surfactants is also provided.
