Regenerative peripheral nerve interfaces have been proposed as viable alternatives for the natural control and feel of robotic prosthetic limbs. We have developed a Regenerative Multi-electrode Interface (REMI) that guides re-growing axons through an electrode array deployed in the lumen of a nerve guide. While acute studies have shown the use of the REMI in the rat sciatic nerve, the quality of chronic...
With the increase of accelerator luminosity, the rate requirement for timing MRPC becomes important. Usually MRPCs are assembled with ordinary glass plates of 1.0 mm or thicker, but their rate capability is only about 200 Hz/cm2, which cannot afford to the future high rate requirement. DC model and a two dimensional resistor network model suggested that the rate capability of MRPC is largely dependent...
The effects of fluorination on the vacuum surface flashover voltage (Uf) of polyimide (PI) are researched. The experimental results show that as the degree of fluorination increases, the Uf of PI firstly increases and then decreases, the highest Uf in the experiments is increased by up to 21 % compared with untreated PI sample. The results of Fourier-transform infrared spectroscopy (FTIR) and X-ray...
This paper demonstrates an acoustic sensor that can resolve atomic force microscopy (AFM) tip blunting with a frequency sensitivity of 0.007%. The AFM tip is fabricated on a thin film piezoelectric aluminum nitride (AlN) membrane that is excited as a film bulk acoustic resonator (FBAR). We demonstrate that cutting 0.98 μm off of the tip apex results in a resonance frequency change of 0.4MHz at 6.387GHz...
