Thermoelectric thin films are candidate materials that can be used to supply the energy harvested to autonomously power Internet of Things (IoT) sensors and devices. This work deals with the fab ... Read More
Piezoelectric materials are utilized for high-power ultrasonic devices such as ultrasonic motors, which are driven under high stress and strain. The nonlinear elastic vibration of piezoelectric ... Read More
Wireless sensor networks (WSNs) are one of the key factors in realizing an Internet of Things (IoT) society. Piezoelectric materials that can convert mechanical energy into electric energy direc ... Read More
The combination of piezoelectric aluminum nitride (AlN) films with flexible substrates made of stainless steel (SUS) foils has been applied in low-frequency and robust microdevices, especially in ... Read More
We build an equivalent Simulation Program with Integrated Circuit Emphasis (SPICE) model for a vibrational energy harvester comprising comb electrodes coated with an electret film that is used to ... Read More
In this work, we focus on the experimental evaluation of the bipolar surface potential in a MEMS electret vibration energy harvester. Bipolar charging increases the absolute electrical energy of ... Read More
In this research, we propose a piezoelectric polymer multilayer coating method by solution casting and spin coating to improve the fabrication yield and piezoelectricity of the vibration energy h ... Read More
In this paper, we present ferroelectric dipole electrets (FDEs) with patterned Pb52(Zr,Ti)48O3 (PZT) pillar arrays. Their output power generation capability was higher than that of flat FDEs whe ... Read More
In this work, new conductive polymer films suitable for microfabrication have been developed. The solutions used are prepared by dispersing highly conductive nanoporous carbon blacks (n-CBs) in ... Read More
In this study, we developed a triboelectric nanogenerator (TENG) for intelligent tires. This TENG was attached on the inner surface of a racing cart tire. First, we evaluated the dependences of ... Read More
A gyroscopic power generator that self-accelerates its spinning velocity via positive power feedback is developed. In our previous study, a power of 1.8 W was generated for a gyro-generator, but ... Read More
