Impedance Monitoring of Bacterial Activity

Monitoring activity of Drosophila larvae : Impedance and video microscopy

Rapid detection of bacterial growth in blood samples by a continuous-monitoring electrical impedance apparatus.

A growth detection method utilizing an automated apparatus capable of rapidly detecting bacterial growth by measuring changes of electrical impedance in bacteriological medium was utilized with "mock" blood cultures containing various gram-negative and gram-positive bacteria. Measurement of changes of electrical impedance was found to ba as accurate and comparable for time of growth detection a...

Early detection of bacterial growth in blood culture by impedance monitoring with a Bactometer model 32.

A Bactometer model 32 was evaluated for use in early detection of bacterial growth. Experiments with simulated cultures showed that 2 ml of broth introduced into the Bactometer module wells could detect 10(2) and 10(6) CFU/ml in 6 h and 2 h respectively. Both Brain Heart Infusion (BHI) and Fastidious Anaerobic broths supported good growth. Detection of nine of 10 organisms inoculated at approxi...

Impedance-based Structural Health Monitoring

1. Introduction The development of a real-time, in-service structural health monitoring and damage detection technique has recently attracted a large number of academic and industrial researchers. The goal of this research is to allow systems and structures to monitor their own integrity while in operation and throughout their lives in order to prevent catastrophic failures and to reduce the co...

Monitoring the chest with impedance.

The application of bioelectric impedance to the measurement of tissue volume changes, long discussed, is with today's electronics innovations now a reality. The theory of this noninvasive technique is conceptually explained. Its application to continuous monitoring of the chest is described using three impedance devices, one of which was designed and developed by us. Clinical cases are describe...
