SIMULATION-BASED PRODUCT DEVELOPMENT FIGURE 1 FIGURE 2 FIGURE 4 FIGURE 3 calculate the channel attenuation in a frequency range between 40 kHz and 20 MHz. The results in Figure 4 show the positions of the right atrium (RA) capsule of the worst-case scenario (perpendicular) and the best-case scenario (parallel). The best-case scenario shows a higher differential voltage across the receiving dipole. The attenuation levels of both scenarios can be seen in Figure 5, where the difference is ~11 dB. From 40 kHz to 20 MHz, the attenuation decreases by ~5 dB for both cases. From the results, Maldari and his team were able to verify that relative position and orientation of the capsules strongly impacts the channel attenuation. For MicroPort, it was important to estimate the attenuation levels before preparing the prototype. " As researchers and scientists, we try to reduce the amount of animal trials, and simulation has allowed that, " said Maldari. " It is a powerful tool to estimate the behavior of the signals within biological tissues before investigating them experimentally. " The use of simulation allowed the team to define accurate models for galvanic IBC communication and optimize transceivers for LCP systems. » FUTURE PLANS FOR IBC MicroPort's future plans involve further studies, where the effect of certain input parameters - such as the electrode size FIGURE 5 and dipole lengths - on a more complete set of electric field parameters will be investigated. This would help them point out the attenuation difference between diastolic and systolic periods. As of now, the researchers are working on the design of an ultralow power receiver for LCP synchronization purposes. The new receiver could potentially mark groundbreaking innovation for dualchamber pacemakers. COMSOL NEWS 25a Intro Cov ToCToC + - A ➭ ➮http://info.hotims.com/79418-936
