We developed an integrated chip for real-time amplification and detection of nucleic acid using pH-sensing complementary metal-oxide semiconductor (CMOS) technology. Here we show an ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

The University of Glasgow has created a pH sensor for soil testing that can be composted at the end of its life. It is an impedance-based sensor, using screen-printed interdigitated carbon-based ...
