All scientific research needs to go through years of arguments and debates to polish itself, including research of functional magnetic resonance imaging (fMRI) in human brain. fMRI is one of the state-of-the-art noninvasive techniques to investigate brain functions of human and animals. Since it is difficult and hardly practical to record vivo neural activity from human brain, fMRI provides an substitute measurement of neural activity which is based on the haemodynamic response in blood flow during the neural activity, also known as bloodoxygen-level dependent (BOLD) signal.

Functional magnetic resonance imaging (fMRI) has been widely used to study human tactile perception. To reveal many unsolved problems to human tactile perception, developing complex and fMRI-compatible stimulation devices are crucial for tactile perception research. These stimulation devices, combined with functional magnetic resonance imaging (fMRI), can assist researchers in analyzing human brain activity. Through analyzing human brain activity, researchers can clarify how the human brain controls the body. Meanwhile, these device scan provide the best rehabilitation program for patients. This chapter presents previous fMRI-compatible stimulation devices, including texture stimulation, shape stimulation, vibrotactile stimulation, etc., which involve the hands, face, ears, legs and other parts of the body. In this chapter, we examine the design of the devices in greater detail. Finally, we summarize the characteristics of these devices and create an outlook for future fMRI-compatible devices.
