TL;DR: In this article, the micro-machinability and edge chipping mechanism on a (001) silicon were investigated by full slot milling using the natural diamond tool, and three chipping types were observed, and its mechanism is attributed to cleavage and slip structure within silicon's crystal architecture.

TL;DR: In this paper, a novel hybrid technique that combines mechanical machining and the deposition of a layered sacrificial structure on the silicon surface has been proposed to minimise the machining-induced edge chipping.

TL;DR: A low power neural engine with an optimized set of algorithms which can operate under a power cycling domain and is integrated with a custom-designed brain implant chip and demonstrated the operational applicability to the closed-loop modulating neural activities in in-vitro and in- vivo brain tissues.

TL;DR: A flexible, transversal intraneural tungsten:titanium electrode array for acute studies is introduced and it is shown that the stimulation of peripheral nerves with this electrode array is possible and that more than half of the electrode contacts can yield a stimulation selectivity index of 0.75 or higher at low stimulation currents.

TL;DR: A new hybrid microfabrication technique which combines ultra-precision micro-milling and a ductile sacrificial material deposition process to fabricate a silicon-based implant for neuroprosthetics applications with near defect-free quality at several hundreds of micrometres in thickness is introduced.
