碩士 === 國立成功大學 === 機械工程學系碩博士班 === 90 === Abstract
Cuff electrode is an important component of motor neural prostheses.
It can directly stimulate sensory and motor neurons or sense signals from
nerve fibers. The goal of this thesis is to design and fabricate a spiral cuff
electrode with embedded micro-pressure sensor by using
micro-electro-mechanical system (MEMS) technologies. Multi-channel
cuff electrodes may enhance the selectivity of sensing nerve signals. For
on-line health monitoring of nerve, capacitive pressure sensors are
developed to detect the pressure on the interface between muscle and
nerve.
The spiral cuff electrode was employed for measuring signals of the
sciatic nerve of New Zealand rabbits and feasibility of multi-channel of
spiral cuff has been proven. Studies of animal model have shown that the
developed cuff electrode is capable of detecting the electroneurogram
(ENG) with less level of noise as compared with our previous results. The
multi-channel ENG can be further decomposed to differentiate
dorsi-flexion and plantar flexion of rabbit ankle. The dimension of spiral
cuff electrodes was 25mm x 12.56mm. Twelve contact electrodes of a
spiral cuff electrode were fabricated and the area of each contact
electrode was 800 800 × µm. The capacitive pressure sensor was designed
by the finite element analysis. The capacitive pressure sensor has a
sensing electrode of 700 µm2, a dielectric layer with thickness of 4 µm,
and a sensitivity of 1.044x10-3pF/mmHg-pF
in the range of 0 to 100mmHg.
