Becerra Fajardo, Laura; Schmidbauer, Marieluise; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2016)Existing implantable stimulators use powering approaches that result in stiff and bulky systems or result in systems incapable of producing the current magnitudes required for neuromuscular stimulation. This hampers their ...

Becerra Fajardo, Laura; Minguillon, Jesus; Rodrigues, Camila; Barroso, Filipe O.; Pons, José L.; Ivorra Cano, Antoni, 1974- (Springer, 2020)Wireless active implantable medical devices (AIMDs) can be an alternative for overcoming the drawbacks faced with superficial and percutaneous technologies. However, current AIMDs require bulky and rigid components for ...
-
Becerra Fajardo, Laura; Ivorra Cano, Antoni, 1974- (Public Library of Science (PLoS), 2015)Electrical stimulation is used in order to restore nerve mediated functions in patients with neurological disorders, but its applicability is constrained by the invasiveness of the systems required to perform it. As an ...

Eladly, Ahmed Fayed; Del Valle, Jaume; Minguillon, Jesus; Mercadal, Borja; Becerra Fajardo, Laura; Navarro, Xavier; Ivorra Cano, Antoni, 1974- (IOP Publishing Ltd., 2020)Objective. It is known that multi-site interleaved stimulation generates less muscle fatigue compared to single-site synchronous stimulation. However, in the limited number of studies in which intramuscular electrodes were ...
-
Becerra Fajardo, Laura (Universitat Pompeu Fabra, 2016-10-17)Neuroprostheses based on dense networks of wireless microstimulators have been proposed in the past for restoring movement in paralysis patients. Yet existing implantable microstimulators are too bulky and invasive for ...
