DESCRIPTION:Dr Denys Nikolayev\n\n\nAbstract\nImplantable neuro- and bioel
 ectronic devices rely on reliable communication with external systems. How
 ever\, two major challenges limit their long-term use: wired connections i
 ncrease infection risk and restrict natural movement\, while wireless solu
 tions typically rely on bulky batteries that can occupy up to 90% of devic
 e volume. Even rechargeable approaches often require large subcutaneous mo
 dules\, leading to complex surgical procedures. In this seminar\, I will p
 resent our research aimed at enabling a new generation of adaptive wireles
 s\, battery-free bioelectronic devices that are highly miniaturizable and 
 capable of long-term operation. Such technologies could unlock minimally i
 nvasive neural interfaces\, injectable bioelectronics\, distributed adapti
 ve sensing/actuating networks\, and new classes of microrobotic systems. O
 ur approach integrates advances across three complementary areas: (1) the 
 physics of wave propagation and control in complex biological media\, (2) 
 programmable radiating and wave-guiding systems enabling adaptive energy d
 elivery and data links for implantable and wearable bioelectronics\, and (
 3) translation into real-world biosensors and bioelectronic platforms thro
 ugh collaborations with clinicians and industry. Through this interdiscipl
 inary framework\, we investigate the fundamental mechanisms governing elec
 tromagnetic radiation and energy transfer for devices embedded deep within
  brain and body tissues. The resulting models reveal key parameters and de
 sign rules that define the achievable limits of wireless efficiency in neu
 ral interface systems. Building on these insights\, we have developed adap
 tive wireless architectures that enable efficient powering and communicati
 on with deep-body devices without batteries. Our results show that wireles
 s efficiency (and therefore the available power budgets and functionality 
 of bioelectronic systems) can be improved by orders of magnitude compared 
 with conventional approaches. These advances open new opportunities for ad
 aptive neurotechnologies and bioelectronic medicine\, enabling long-lastin
 g\, minimally invasive platforms for neural interfacing\, physiological se
 nsing\, and precision neuromodulation.\n\nBio\nDenys Nikolayev is a CNRS 
 researcher leading the Wireless Bioelectronics group at the IETR laborator
 y (France). His research focuses on adaptive wireless neuro- and bioelectr
 onic technologies that enable minimally invasive neural interfaces\, distr
 ibuted biosensing\, and battery-free implantable devices. By combining wav
 e physics\, RF engineering\, and bioelectronics\, his work has established
  fundamental limits of wireless energy transfer in biological tissues and 
 enabled new architectures for deep-body wireless systems. His research is 
 supported by an ERC Starting Grant and several national and industrial pro
 grams\, and it has resulted in multiple patents and technology transfer to
  medical device companies. He collaborates broadly with clinicians and eng
 ineers to develop next-generation neurotechnology and bioelectronic medici
 ne platforms.\n
