Background technique

Functional Magnetic Resonance Imaging, or fMRI for short, is an emerging neuroimaging method. Its principle is to use magnetic resonance imaging to measure hemodynamic changes caused by neuronal activity. Due to the advantages of non-invasiveness and no radiation, fMRI has been widely used in human functional structure and brain map research in the visual, auditory, somatosensory cortex and parietal cortex since the 1990s.

Compatibility issues of equipment under type and strong magnetic field.

Currently, MRI-compatible devices for tactile stimulation of the hand include piezoceramic and pneumatic devices. The piezoelectric stimulator is a stimulator developed based on the piezoelectric effect. It uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy, and then generates mechanical vibrations to generate tactile stimulation. As for the pneumatic type, most of the existing pneumatic devices use the principle of diaphragm vibration to provide tactile stimulation, and a few use the nozzle directly fixed on the stimulation site to stimulate by jetting.

Although the piezoelectric vibratory tactile stimulator cannot be finely adjusted according to the demand, the adjustment accuracy is low; for the pneumatic diaphragm stimulator, the distance between the nozzle and the skin surface and the stimulation position of the few stimulators that use jet stimulation are both It is fixed and cannot be adjusted arbitrarily, and it is impossible to ensure that the nozzles maintain the same distance from the skin, so the accuracy of stimulation is low.

Therefore, the position of the existing tactile brain activity stimulation device cannot be adjusted accurately, resulting in low stimulation accuracy, so it cannot meet the needs of use and is in urgent need of improvement.
