Electrical Model of a Wireless mW-Power and Mbps-Data Transfer System Over a Single Pair of Coils

Alexandre Schmid, David Palomeque Mangut

This paper proposes a system to transfer both mW-power and Mbps-data over an inductive link using a single pair of coils. The system is able to handle a wide range of loads by implementing a load adapter block that divides the operation into two phases: a ...

Dielectric-Loaded Conformal Microstrip Antennas for Versatile In-Body Applications

Anja Skrivervik, Denys Nikolayev

Wireless implantable bioelectronics and accurate in vivo characterization of path loss require efficient and robust in-body antennas. Loading electric antennas with the effective permittivities higher than that of surrounding tissues is a promising solutio ...

Influence of Body-Implanted Capsule Dimensions and Materials on Achievable Radiation Efficiency

Anja Skrivervik, Denys Nikolayev

Fundamental bounds on achievable radiation efficiency serve as the design quality gauge, facilitate the choice of the antenna type considering the available dimensions, and provide simple rules to check the feasibility of a given design. This study quantif ...

Damage mitigation of a near-full-scale deployable tensegrity structure through behavior biomimetics

Ian Smith, Ann Christine Sychterz

Current infrastructure is designed and built such that it must simultaneously comply with all possible loads. This leads to overdesigned structures that are inefficient in terms energy and cost. A structure that can self-identify damage, adapt, and learn f ...

A combined 32‐channel receive‐loops/8‐channel transmit‐dipoles coil array for whole‐brain MR imaging at 7T

Rolf Gruetter, Özlem Ipek, Jérémie Daniel Clément

Purpose Multichannel receive arrays provide high SNR and parallel‐imaging capabilities, while transmit‐only dipole arrays have been shown to achieve a large coverage of the whole‐brain including the cerebellum. The aim of this study was to develop and char ...
