title = "3-D electrode configuration for electrochemical impedance spectroscopy of bulk solution",
abstract = "In this paper, a 3-D electrode configuration for electrochemical impedance spectroscopy (EIS) of a bulk solution was studied. Top- and bottom- electrode configuration, where two electrodes sandwich the sensing channel, was fabricated using the tearing the patterns from the PDMS (Polydimethylsiloxane) stamp to glass substrate approach [1] and implementation of glass via. Impedance of fabricated glass via was evaluated from 40 Hz to 110 MHz using the impedance analyzer. Measured impedance ranges from 0.3 Ωat40 Hz to 79.0 Ω at 110 MHz, which was feasible in electrochemical impedance spectroscopy. The tearing of the patterns from the PDMS (Polydimethylsiloxane) stamp is also shown to be an effective fabrication method for microfluidic channels for top- and bottom- electrodes. The device with a 100 pm height sensing channel was studied with DI water and KCL (concentration of 10-3, 10-2, 10-1 M) for verifying the sensing performance.",
