Abstract
This paper reports on the fabrication method of a micro solenoid coil as a receiver for MRI (Magnetic Resonance Imaging). The micro solenoid coil is consists of upside arcs and downside arcs formed by bending the flexible substrate, a selective assembly mechanism of PDMS (Poly Di Methyl Siloxane), an acrylic fixture. The downside arc of the coil was assembled selectively by fixing only the central part to the selective assembly mechanism. Since the hinge structures with low bending stiffness was located at both ends of downside arc, the cross section of the micro solenoid coil became circular. We fabricated a micro solenoid coil of 20 mm in diameter with a circular cross section. As a demonstration of MRI by the fabricated coil, we acquired MR images of an okra.
