Abstract
Motion detector comprising a flexible support (1,5) adapted to hold at least one object (6-9), a sensor (4) for measuring the displacement of said support (1) and processing means for differentiating the fluctuations of said support (1) from those induced by said object (6-9).
Claims12
A method for analyzing a biological object with a motion detector, the motion detector including a flexible support, a sensor for measuring fluctuations of the flexible support, and electronics for analyzing the fluctuations, the biological object consisting of bacteria or cells, in presence or absence of external or internal stimuli, the method comprising the steps of:
- bringing the biological object into contact with the flexible support, the biological object imparting a nanoscopic motion,
- measuring the fluctuations of the flexible support with the sensor while the biological object is in contact with the flexible support, the fluctuations being caused by the nanoscopic motion imparted by the biological object;
- analyzing the statistical variance of the measured fluctuations by the electronics;
- and
- determining a viability of the biological object based on the analysis of a statistical variance of the measured fluctuations.
