The desired goal is to evoke specific tactile sensations selectively stimulating skin receptors by means of an electric current in place of mechanical stimuli. The field of application ranges from functional magnetic resonance imaging (fMRI) tactile studies to augmented reality technology. The device here proposed is designed using safety criteria in order to comply with the threshold of voltage and current permitted by regulations. Moreover, MR safety and compatibility criteria were considered in order to perform experiments inside the MR scanner during an fMRI acquisition for functional brain activation analysis. Psychophysical laboratory tests are performed in order to define the different evoked tactile sensation. After verifying the device MR safety and compatibility on a phantom, a test on a human subject during fMRI acquisition is performed to visualize the brain areas activated by the simulated tactile sensation. date: 2006 event_title: EMBS Annual International Conference event_location: New York event_dates: 30 Aug - 03 Sep 2006 event_type: conference id_number: 10.1109/IEMBS.2006.260279 refereed: TRUE isbn: 1-4244-0032-5 book_title: Proceedings of the 28th IEEE EMBS Annual International Conference official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=4461928 citation: Hartwig, Valentina and Cappelli, Claudia and Vanello, Nicola and Ricciardi, Emiliano and Scilingo, Enzo Pasquale and Giovannetti, Giulio and Santarelli, Maria Filomena and Positano, Vincenzo and Pietrini, Pietro and Landini, Luigi and Bicchi, Antonio A compatible electrocutaneous display for functional magnetic resonance imaging application.
