32times32 acetylcholine image sensors were successfully fabricated by using the CCD/CMOS image sensor technique, and real time imaging of acetylcholine distribution was carried out without label and a huge measurement. Acetylcholine imaging technology has a lot of potential for the early stage of Alzheimer's disease, the release mechanism between terminal neurons. In addition, the proposed sensor...
This paper presents a very thin silicon dioxide microtube electrode array, which has sub ten-micrometers in inner diameter, as a neural interface device with high signal-to-noise ratio and low invasiveness. The device was realized by using out-of-plane silicon dioxide microtube arrays fabricated from vapor-liquid-solid growth and microfabrication techniques. Here we report advantages of electrical...
We developed a batch-fabrication of nanoscale-tip silicon microprobe arrays for use in multipoint nanoscale investigations of cell/neuron in-vivo/in-vitro. Sharpened tips, less than 100nm diameter, can be formed at the tips of out-of-plane three-dimensional silicon microprobe (length >10mum) arrays, by silicon wet etching-based batch-process within only 1-3min, providing precisely controlled tip...
We report applications of sub-5 μm diameter silicon microprobes and silicon dioxide microtubes fabricated by vapor-liquid-solid method and microfabrication techniques, to use in in-vivo animal experiments. Before animal experiments, electrical impedance and test signal detection via the microprobe electrode were investigated. According to the results, electrical impedance at 1 kHz is approximately...
This paper describes a device design, fabrication, experimental results, and mechanical strength for a multi functional device of neural behavioral analysis. The device has been fabricated with Si micro probe of 2 mum in diameter and SiO2 micro tube of 3.6 mum in outer diameter on circuit of MOSFETs, using standard IC process followed by a selective VLS growth and MEMS techniques. MOSFETs' performance...
This paper reports on the development of neural recording chip device with penetrating Si microprobe electrode array using IC-process. The Si microprobe electrode array each with a few microns in diameter was grown at predetermined positions with interconnection-wirings. Controlling the diameter and the length of Si probes can be realized by a selective vapor-liquid-solid (VLS) growth. In this work,...
