Dr Pa­ciello has a de­gree in elec­tronic engi­neer­ing and a PHD in In­for­ma­tion Engi­neer­ing. He is the As­sis­tant Pro­fes­sor of Elec­tri­cal and Elec­tronic Mea­sure­ments at the Univer­sity of Salerno and has been devel­op­ing elec­tronic sus­pen­sion since 2008, through a spin-off com­pany called Spring Off. In 2016 he be­came As­so­ciate Pro­fes­sor at the Univer­sity of Cassino and South­ern Lazio.

The last few years have seen sev­eral dif­fer­ent types of elec­tronic sus­pen­sion on the mar­ket that use so­le­noid valves to con­trol the flow of damp­ing fluid through the shock ab­sorber or fork leg. Some sim­ply give you man­ual con­trol over the elec­tron­ics by press­ing but­tons to ac­cess dif­fer­ent modes, while oth­ers are connected to an ECU which has a pre-pro­grammed set of math­e­mat­i­cal al­go­rithms, also known as a Con­trol Strat­egy, so

it can send com­mands back to the so­le­noid valves. Where the Mupo Mag­neto sys­tem dif­fers is that it is filled with mag­neto-rhe­o­log­i­cal (MR) fluid and uses elec­tro-mag­nets to change the vis­cos­ity of the damp­ing fluid.

The damp­ing fluid can be made thicker or thin­ner in an in­stant The mag­net acts on tiny iron par­ti­cles in the fluid Changes can be made in just mil­lisec­onds
