摘要
The charge transfer technique, which can operate in the charge accumulation mode, is suitable for pH imaging to detect small changes in potential. An advanced charge-transfer-type hydrogen image sensor consisting of 1024 × 1024 pixels was fabricated. The new pixel design and scanning system achieve a high-density image element with a pixel area of 12.1 × 12.1 μm 2 , which is 73% less than that in our previous work. The pH sensitivity is 29.8 mV/pH when using standard pH solutions. All 1024 × 1024 pixels are capable of measuring hydrogen ions, as demonstrated in a video of hydrogen ion movement on the new sensor chip.
