Microelectronics-embedded channel bridging and signal regeneration of injured spinal cords

Due to the difficulty in spinal cord regeneration with biological methods, the microelectronic neural bridge, a new concept based on microelectronic technology, is presented. The microelectronic system has been realized in the forms of hybrid and integrated circuits. The integrated circuits for neural signal detection, stimulation, and regeneration are realized in a CMOS process. In animal experiments with 100 toads, 48 rats, and 3 rabbits, nerve signals have been successfully detected from spinal cords and sciatic nerves, and functional electrical stimulation has been carried out for spinal cords and sciatic nerves. When the microelectronic system is bridged between the controlling and stimulated nerve, the relevant motion of legs and nerve signal waveforms, which are stimulated by the evoked or spontaneous nerve signal through such a system, have been observed. Therefore, the feasibility of the presented method was demonstrated.

Investigation on the synthesis mechanism of β-FeSi2 prepared by pulsed laser deposition

The FeSi2 target alloy was fabricated by conventional powder metallurgy technology, and then, β-FeSi2 thin films was successfully prepared by pulsed laser deposition (PLD). X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were used to characterize the structure, composition, and their changes in the process of β-FeSi2 preparation. In addition, a laser sintering process was also employed to prepare FeSi2 alloy. The analysis of radiation heat transfers in different-sized FeSi2 melt indicates that the cooling rate of the melt depends on the size, i.e., the cooling rate of the micron sized melt is 103 times greater than that of the millimeter-sized melt. The product α-FeSi2 by laser sintering and β-FeSi2 by PLD reveals the different phase transition process in crystallization of milli-meter-sized and micron-sized (or submicron-sized) FeSi2 melt. The results of PLD preparation process shows that β-FeSi2 could be pre-pared through a liquid-phase sintering, followed by a rapid cooling.
