Established classes of high-performance electronics have driven advances in interventional biomedicine. However, the large size, planar geometry and stiff mechanical properties of standard conventional electronics employed in medical devices give rise to important integration challenges with soft biological tissue. Stretchable and flexible biointegrated electronics could improve treatment procedures...
The arrhythmogenic substrate in patients with prior myocardial infarct (MI) is located at the border zone, BZ. In this study we correlated the BZ identified by two methods: electro-anatomical voltage mapping (EAVM) and a novel MRI method, multi-contrast late enhancement (MCLE). A pre-clinical porcine model with chronic MI was used to characterize BZ via MRI and EAVM. Results focus on the comparison...
The control of pH is widely recognized as a difficult problem. The Strong Acid Equivalent approach for control of pH processes consists of defining an alternate equivalent control objetive, the Strong Acid Equivalent, which is linear in the states and using a linear control law in terms of this new control objective. The Strong Acid Equivalent is then calculated on line from pH measurements given...
The measurement of volume charges within solid insulators provides needed information important to the evaluation of dielectric performance and the modelling of breakdown processes. Furthemore, electrical insulation such as polyethylene can be crosslinked with penetrating electron irradiation and thus be exposed to charge injection. While polyethylene is a widely used dielectric material, especially...
