TL;DR: It is shown how three adaptations of the implant allow for untethered optogenetic control throughout the nervous system (brain, spinal cord and peripheral nerve endings) of behaving mice.

TL;DR: A wireless powering method is reported that overcomes the challenge of energy transfer beyond superficial depths in tissue by inducing spatially focused and adaptive electromagnetic energy transport via propagating modes in tissue and is used to power a tiny electrostimulator that is orders of magnitude smaller than conventional pacemakers.

TL;DR: In this paper, the authors examined the range of frequencies that will optimize the tradeoff between received power and tissue absorption and showed that the optimal frequency is above 1 GHz for small receive coil and typical transmit-receive separations.

TL;DR: The commonly used statistical multiple-input multiple-output (MIMO) model is inadequate and antenna theory is applied to take into account the area and geometry constraints, and to define the spatial signal space so to interpret experimental channel measurements in an array-independent but manageable description of the physical environment.

TL;DR: A bodyNET composed of chip-free and battery-free stretchable on-skin sensor tags that are wirelessly linked to flexible readout circuits attached to textiles that can continuously analyse a person’s pulse, breathing and body movement is reported.
