We present the development of an eight-channel microcoil array as a prototype for the simultaneous detection of signal from samples at predefined spatial positions. The manufacturing process is fully MEMS compatible, therefore being cost-effective and making the array suitable for one-time usage. Eight microcoils have been selected for this study, but the number of coils (i.e. positions) could be extended to the maximum number of receive channels provided by the MRI spectrometer. By varying size, number and mutual distance of the microcoils, such a multi-coil array can be used for testing detection schemes of parallel imaging techniques.
