英文摘要: A new micro embedded telemetry system was developed for the amperometric sensing detection. Its output voltage range was +/- 0. 5 V and resolution was < 1 mV. The current acquisition range was +/- 1 mu A and the minimum resolution was 0. 2 nA. This telemetry system was designed based on microprocessor ADuCM360, including a potentiostat, a current detection module and a radio module. And the size was only 24 mm. 13 mm. 11 mm. The computer software written in LabVIEW language was used for data storage and display. In order to verify the accuracy and reliability of this system, an electrical performance test was performed. The current response for ascorbic acid with different concentration was recorded by using the telemetry system. The potential of working electrode was set as 30 mV, and the current response of ascorbic acid electrode had a good linear relationship with its concentration within the concentration range of 50-300 mu mol/L. Linear equation was I(nA) = 2. 98C(AA) (mu mol/L) - 137. 39, and linear correlation coefficient R-2 = 0. 984. Moreover, the applicability of the instrument in the study for living animals was explored by using the cerebral ischemia as model.
