Enabling Covert Body Area Network using Electro-Quasistatic Human Body Communication | Scientific Reports
Interesting body area network concept, but the range limits for an adversary depend a lot more on noise floor and antenna quality. Though I suppose this making it hard enough that someone normally needs to touch you to connect may be enough of a security hurdle...

Uses a low power FM radio as a long-ish range outdoor mesh network repeater/range extender thingy to connect smartphones in the wilderness. Only does voice and text messaging though, but considering the underlying bandwidth that's pretty good.

LTE Direct Research Project
So a bad mix between ham radio and iBeacons, but you can't randomize your MAC address (IMEI) so you are always identifiable. Won't work for protest situations as a carrier can functionally prohibit by disabling authorization for spectrum. Might be nice for disasters to form mesh networks assuming the authorization infrastructure survives.

Sonardyne announces collaboration with WHOI engineers to launch a unique subsea optical communication technology – BlueComm
No company website yet, but Lumasys will be fielding commercial versions of BlueComm, a 200m range underwater blue LED optical communications platform, capable of 20Mbps. Matching this up with both TCP/IP, and delay tolerant networking (DTN) would make this really useful for underwater ROV teleoperation. Unfortunately, probably still defeated by a container full of tape in the bandwidth department, but beats the pants off acoustic systems (if you can tolerate the range limit or can employ a relay mesh network).

Developing power-over-fiber communications cable: When total isolation is a good thing – Sandia Labs News Releases
Low power for now, but allows remote powering of sensors and provides data transmission capabilities, all in one cable. Endgame probably is a prism on the sensor end, splitting off power frequencies to the photovoltaic power cell, and the communication frequencies to the optical data sensor.

SonicNotify: Creating media in presence
Using embedded ultrasonic coded data to transmit information to smartphones, this is the audio equivalent to the QRcode. May have potential a digital watermark on live event music/audio streams. The advertising possibilities are almost endless, since any advertising URL's are automatically embedded (provided your particular audio codec which you use for recording doesn't strip ultrasonics out).

Spray On Kit
Apparently this is the real deal, a nanoparticle/nanocapacitor suspension paint. A spray on paint kit to create either a conformal antenna or to enhance an existing antenna. They painted a tree and were able to send VHF signals 14 miles. Boosting existing antennas is anywhere from 10% to 40% (40% was 20dBm for an iPhone 3 test). The videos also talk about potential uses in other EMF applications, such as (?AC) electric motor windings.
