Traditionally\, biomedical devices use batteries as a power source. T herefore\, every battery replacement requires surgery. The concept of seam lessly delivering power within the human body through implanted coils and antennas has opened a new frontier in healthcare\, enabling the developmen t of innovative medical devices and systems.\n\nSome applications of impla nted wireless power transfer technology include implantable medical sensor s\, monitoring devices\, drug delivery systems\, and neurostimulators. The implanted coils and antennas ensure these medical devices function optima lly without the need for invasive procedures for battery replacement or re charging.\n\nWhen it comes to wireless power transfer\, there are two majo r methods used in implanted devices. One is magnetic field coupling\, whic h uses coils\, and the second method involves electromagnetic waves transf erred through antennas. The development of these components demands carefu l consideration of factors such as miniaturization\, biocompatibility\, an d efficient power transfer over varying distances and orientations within the human body. Magnetic coupling offers high power transfer efficiency bu t is limited by the depth at which power can be effectively transferred. B eyond a certain depth\, efficiency drops significantly. Radiative power tr ansfer via electromagnetic waves can transfer power over larger distances\ , but its efficiency may become very low.\n\nAn interesting research topic is how to take advantage of both methods to extend the range of power tra nsfer while optimizing power transfer efficiency. Another primary focus in this field is the development of safe and efficient systems that comply w ith safety regulations. Particularly\, the regulated levels of exposure in terms of Specific Absorption Rate (SAR) are critical considerations in th e design and implementation of these technologies.\n\nTo improve power tra nsfer efficiency\, careful modeling and simulation of these devices is ess ential\, as well as rigorous testing in phantom and laboratory environment s. This talk aims to explore some of these topics\, considering the signif icance\, challenges\, and potential of wireless power transfer technology for implanted devices.\n\nSpeaker(s): Dr. Sima Noghanian\n\nRoom: B-600.16 \, Bldg: Pavillion Principal\, Galerie Rolland (B-600.16)\, 2500 Chem. de Polytechnique\, Montréal\, Quebec\, Canada\, H3T 1J4\, Virtual: https://e vents.vtools.ieee.org/m/560674 LOCATION:Room: B-600.16\, Bldg: Pavillion Principal\, Galerie Rolland (B-60 0.16)\, 2500 Chem. de Polytechnique\, Montréal\, Quebec\, Canada\, H3T 1J 4\, Virtual: https://events.vtools.ieee.org/m/560674 ORGANIZER:elham.baladi@polymtl.ca SEQUENCE:30 SUMMARY:Seamless Power: Implanted Antennas for Biomedical Wireless Power Tr ansfer URL;VALUE=URI:https://events.vtools.ieee.org/m/560674 X-ALT-DESC:Description: <br /><p class="MsoNormal" style="text-align: justi fy\; line-height: normal\; margin: 6.0pt 0in 6.0pt 0in\;"><span lang="EN-U S" style="font-family: 'Calibri'\,sans-serif\;">Wireless power transfer ha s emerged as a transformative technology.
