Implantable wireless neural recording from a large ensemble of simultaneously acting neurons is a critical component to thoroughly investigate neural interactions and brain dynamics from freely moving animals. Recent researches have shown the feasibility of simultaneously recording from hundreds of neurons and suggested that the ability of recording a larger number of neurons results in better signal quality. This massive recording inevitably demands a large amount of data transfer. For example, recording 2000 neurons while keeping the signal fidelity ( > 12 bit, > 40 KS/s per neuron) needs approximately a 1-Gb/s data link. Designing a wireless data telemetry system to support such (or higher) data rate while aiming to lower the power consumption of an implantable device imposes a grand challenge on neuroscience community. In this paper, we present a wireless gigabit data telemetry for future large-scale neural recording interface. This telemetry comprises of a pair of low-power gigabit transmitter and receiver operating at 60 GHz, and establishes a short-distance wireless link to transfer the massive amount of neural signals outward from the implanted device. The transmission distance of the received neural signal can be further extended by an externally rendezvous wireless transceiver, which is less power/heat-constraint since it is not at the immediate proximity of the cortex and its radiated signal is not seriously attenuated by the lossy tissue. The gigabit data link has been demonstrated to achieve a high data rate of 6 Gb/s with a bit-error-rate of 10(-12) at a transmission distance of 6 mm, an applicable separation between transmitter and receiver. This high data rate is able to support thousands of recording channels while ensuring a low energy cost per bit of 2.08 pJ/b.

“…However, due to its high rigidity, a hollow metal pipe creating total reflection at the metal boundaries is expensive and inconvenient. In contrast, a dielectric waveguide, although flexible and easy to use 14 , it has not been considered as an alternative for the conductor based interconnects due to 1) poor manufacturability 15 16 and 2) low power efficiency 17 caused by limited bandwidth-to-centre frequency ratio and 3) intrinsic energy loss due to the field leakage and high bending loss caused by refraction occurring at the boundaries of the bended dielectric waveguide.…”

The ever-increasing demand for bandwidth triggered by mobile and video Internet traffic requires advanced interconnect solutions satisfying functional and economic constraints. A new interconnect called E-TUBE is proposed as a cost-and-power-effective all-electrical-domain wideband waveguide solution for high-speed high-volume short-reach communication links. The E-TUBE achieves an unprecedented level of performance in terms of bandwidth-per-carrier frequency, power, and density without requiring a precision manufacturing process unlike conventional optical/waveguide solutions. The E-TUBE exhibits a frequency-independent loss-profile of 4 dB/m and has nearly 20-GHz bandwidth over the V band. A single-sideband signal transmission enabled by the inherent frequency response of the E-TUBE renders two-times data throughput without any physical overhead compared to conventional radio frequency communication technologies. This new interconnect scheme would be attractive to parties interested in high throughput links, including but not limited to, 100/400 Gbps chip-to-chip communications.

A millimetre-wave interconnect on a very low-cost plastic waveguide is proposed for applications in terabit per second wireline links. Simultaneous utilisation of the two fundamental and polarisationorthogonal degenerate E x 11 and E y 11 waveguide modes doubles the capacity of a single line without sacrificing robustness or adding implementation cost and complexity. A prototype of the structure has been fabricated in high-density polyethylene (HDPE) fed with dipole/slot coupling structures on Rogers RO6006, and operates at frequencies of about 75 GHz with an aggregate 3 dB bandwidth exceeding 60 GHz.
