A micro time of flight (TOF) electrochemical impedance (EI) flow sensor μEIFS suitable for implantation and integration with a catheter was developed. The transducer utilizes two pairs of electrodes to monitor using EI measurement the passage of a gas bubble generated upstream. High precision measurement of bubble TOF (SD <; 6% of mean) was achieved over… CONTINUE READING
