Impedance measurement of live biological cells is widely accepted as a label free, non-invasive and quantitative analytical method to assess cell status. This method is easy-to-use and flexible for device design and fabrication. In this review, three typical techniques for impedance measurement, i.e., electric cell-substrate impedance sensing, Impedance flow cytometry and electric impedance spectroscopy,...
In this paper, we used an experimental platform based on cellular impedance sensors to study cellular changes after hyperthermia treatments. Impedance profiling showed high correlation with traditional MTT results, thus the impedance data represent cell viabilities very well. Then, status of cells under six typical hyperthermia treatments with different temperatures between 41–46 °C and different...
Label-free and rapid analysis of a large-scale cells is essential for single-cell analysis and the point-of-care testing (POCT). We demonstrated a microchip-based impedance flow cytometer for cell identification and counting in single-cell level without labelling. Cells were focused to sequentially flow through a straight channel in a disposable chip. One pair of coplanar sensing electrodes underneath...
A microfluidic device for single mouse embryo manipulation was fabricated and the impedance spectroscopy of the positioned embryo was detected by the electrodes in the microchannel. Experiment results showed that the impedance of embryo varies when it is at different stage. Also, healthy embryos and development-blocked embryos showed different impedance spectroscopy. Compared with the traditional...
A new method is reported for human muscle force modeling based on the fuzzy theory. First, a Hill-based muscle force model was built. The muscle activation parameters were ascertained by fuzzy inferential algorithm as the input of the Hill-based muscle force. Then, a weightlifting motor task was implemented. Four channels of electromyography signals and twelve virtual markers motion data were collected...
