“…The proposed pH image sensor, with which it is possible to construct a two-dimensional (2-D) pH image, can be fabricated using semiconductor integrated circuit technology and recording a visible pH image in real time can be achieved by using CMOS image sensor technology. Previously, we proposed chemical sensors to measure pH using a charge transfer technique [6,7]. The signal output of accumulation method ion sensor (AMIS) is possible to accumulate pH signal as charges.…”

“…Among these variants, charge-transfer-type ion-sensor devices [9], [10] exhibited higher sensitivity by making use of the charge accumulation technique. Our studied the chargetransfer-type ion image sensors with a photo-image acquisition function [11], [12], and applied them to the field of biochemical analyses [5], [13].…”

“…Previously, we proposed and presented a charge-transfer type pH sensor, which could transduce a chemical potential through pH to determine charge quantity [1]. The charge-transfer type sensor was applied as a highly sensitive ion sensor [2], as a fused sensor for optical and ion sensing [3], and as 32×32 arrayed pH imaging sensor [4]. In addition, we developed a multi-wavelength detection sensor [5,6], which could be applied for the detection of fluorescence.…”
