SARTI-MAR - Sistemes d'Adquisició Remota de dades i Tractament de la Informació en el Medi Marí
El grup de recerca SARTI-MAR té com objectiu fonamental el desenvolupament de instrumentació científica de paràmetres ambientals, amb especial èmfasi en el medi marí. Gràcies a les infraestructures desenvolupades al voltant del observatori submarí Obsea (www.obsea.es), existeix una forta interacció entre col·lectius d’enginyers i científics, nacionals e internacionals. Interacció orientada a l'estudi dels processos oceànics relacionats amb els ecosistemes marins, el canvi climàtic i els riscos mediambientals. Les tecnologies de mesura dels observatoris submarins permeten obtenir dades amb prou resolució temporal per registrar esdeveniments "singulars" però claus en la dinàmica dels processos i obtenir la informació in situ per analitzar fenòmens específics. La capacitat d'abastar un ventall tant ampli d'escales espai-temporals d'observació proporciona noves oportunitats de recerca i desenvolupament, tant en projectes de recerca bàsica com en innovació tecnològica.

Performance of WAVY ocean Lagrangian drifters for surface characterization of ocean dynamic structures
(Institute of Electrical and Electronics Engineers (IEEE), 2022-10-05)
Conference report
Restricted access - publisher's policyLow-cost drifters can measure ocean surface waves thanks to global navigation satellite systems (GNSSs) and new motion-sensor packages. Drifting along or across current gradients allows for unique in-situ wave–current ... -
Effect of the sampling parameters in FOCV-MPPT circuits for fast-varying EH sources
(Institute of Electrical and Electronics Engineers (IEEE), 2022-10-20)
Article
Restricted access - publisher's policyThe fractional open circuit voltage (FOCV) method is extensively used in low-power energy harvesting (EH) sources to extract maximum power. For fast-varying EH sources a fast sampling rate is required. This work theoretically ... -

A new nonlinear compliant mechanism for harvesting energy from ocean waves
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference lecture
Open AccessTraditonal linear oscillators, such as cantilevers or pendulums, are only sensitive to specific resonant frequencies. They have then very narrow frequency bandwidths when harvesting energy from ocean waves. In order to ...
