Extremely thin, lightweight, and flexible receive arrays can be achieved by the use of printed electronics. Coil arrays printed layer-by-layer from solution have shown potential to deliver a comfortable customized fit for many patients. However, relatively low SNR and poor mechanical robustness prevented these devices from performing to their full potential. Here we offer SNR within 3% of a traditionally made coil by using high quality polymeric films as dielectric layers in capacitors, high conductivity inks, and a mechanically robust fabrication processes using fewer printed layers and stronger connections. Using these techniques shoulder and elbow images of a volunteer were obtained.
