The sensor has an electrochemical cell that is composed of a reference, an auxiliary and two working electrodes on a spin-coated polyimide film, where the reference electrode is silver and the others are platinum. The polyimide film is used for antibody immobilization instead of a polystyrene sheet which is usually used in conventional immunosensors. A reaction chamber is fabricated separately on a silicon wafer using anisotropic etching techniques. The electrochemical cell on a glass wafer and the reaction chamber on a silicon wafer are then bonded together to construct the immunosensor using polymer bonding techniques. Fabricated immunosensors are tested by the method of cyclic voltammetry (CV) before analyzing the antigen-antibody reaction. Test antibodies are well attached to the polyimide substrate, and the results of the CV test shows that this immunosensor can be successfully applied for electrochemical immunoassay.","PeriodicalId":342750,"journal":{"name":"Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

This paper presents a slip detection method using the power spectrum of spiral cuff ENG. The central toe pad of a cat is used as a model for human glabrous skin. Three modes of tactile stimuli (slip, stretch and pressure) are applied to the central toe pad in an anesthetized preparation while recording the electroneurogram (ENG) from the tibial nerve using a three band spiral cuff electrode. Discriminant analysis of the power spectra of 10 ms data segments was used to classify randomly selected segments as \"slip\" or \"non-slip\". The highest classification rate (81% correct) was achieved by normalizing the power spectra by the total power of the segment. Three window sizes (10 ms, 20 ms and 40 ms) were compared and found to have no effect on classification rate. The classification rate appeared to correlate well with the velocity of the slipping object, ranging from 55% to 90% for velocities of 2.5 mm/s to 15 mm/s. In conclusion, the power spectrum can be used to distinguish slip from other types of tactile stimulus and higher velocities are detected more reliably.","PeriodicalId":342750,"journal":{"name":"Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

Each neuron was analyzed using a multi-linear regression model that expressed the instantaneous firing rate of the neuron as a function of the instantaneous 2D position, velocity, and acceleration of the eye. In all cases, the model provided a good description of the data. In addition, the model explains why some neurons show relatively complex responses including a systematic preference for clockwise (CW) versus counterclockwise (CCW) circular target motions, while others low simpler responses. Most neurons had position and velocity preferred directions that were in alignment. These neurons had relatively simple response profiles with similar response amplitudes during CW versus CCW circular pursuit. Other neurons had position and velocity preferred directions that were not aligned and that differed by as much as 90/spl deg/. These neurons had more complex response properties including a preference for either CW or CCW circular pursuit. This suggests that neurons with simple responses receive inputs with similar spatial tuning properties, while complex responses result from inputs with different spatial tuning properties.","PeriodicalId":342750,"journal":{"name":"Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

Six blindfolded subjects were passively accelerated along a horizontal track and instructed to signal when they perceived themselves passing a remembered target. We tested three orientations: upright Y-axis (lateral), and two supine Z-axes (starting acceleration headward or footward). The cart trajectory was specified by a square wave in acceleration. Two acceleration levels (1.0 and 0.2 m/s2) and two target distances (0.8 and 2.4 m) were used. The subjects each performed four repetitions of each set of parameters. We consistently found (501/554) anticipatory responses, with the only late responses occurring on the return path; this agrees with the findings of Israel et al. Footward acceleration produced the greatest anticipation, followed by Y-axis and headward accelerations. However, a striking asymmetry appeared when responses to headward and footward accelerations in the supine orientation were compared to one another. ANOVA on the latencies for both pooled and individual subjects showed orientation as significant (P<0.001). This asymmetry may reflect nonlinearities in the generation or processing of otolith information. Moreover, from a behavioral standpoint, the heightened anticipation during footward motions may be an expression of the human need to be particularly sensitive to downward accelerations, such as falls.","PeriodicalId":342750,"journal":{"name":"Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society.
