Research
I have been involved in circuit design for analog semiconductors, particularly in the development of power supply ICs for mobile devices.
Since mobile devices are battery-powered, their power supply ICs must consume low power and operate at low voltages.
I'm currently conducting research into energy harvesting ICs that take advantage of these characteristics.
Theme1：Power Supply ICs for Energy Harvesting
Overview
Energy harvesting is a technology that extracts energy from objects around us, and is also known as environmental power generation. Currently, a wide variety of sensors are used in a wide range of places, but they require an energy source to operate. Generally, sensors require batteries to operate, but replacing or disposing of these batteries is costly and environmentally unfriendly. Energy harvesting power supply ICs enable battery-less applications by generating electricity using energy sources in the environment. However, the energy form our environment is very small (ex. 1μW or less) and cannot drive sensors as it is. Energy harvesting power supply ICs store a small amount of power and boosts it to a voltage sufficient to drive sensors. This IC makes it possible to operate sensors without a battery and transmit data wirelessly.
