Abstract

Prosthetic limbs are commonly used by people with limb loss (acquired amputation) and limb absence (congenital deficiency) to restore or imbue some of the function and/or cosmesis of an anatomical limb. Prosthesis is part of the field of biomechatronics, the science of using mechanical devices with human muscle, skeleton, and nervous systems to assist or enhance motor control lost by trauma, disease, or defect. Ionomeric Polymer-Metal Composites (IPMC) are attractive type of electroactive polymer actuation materials because of their characteristics of large electrically induced bending, mechanical flexibility, low excitation voltage, low density, and ease of fabrication. The diffusion of ions between the electrodes causes the material to bend. IPMC material acts as the artificial muscle in prosthetic limb. Nerve signals obtained from the natural damaged muscle will be read and amplified so that the IPMC connected to the lost limb will work as per the characteristics of this signal. Electrodes will be attached between the patient limb and the microprocessor, which will analyze nerve signals to be processed and provide the appropriate output to the IPMC. Once nerve signals characteristics are read and reaction from the IPMC is achieved an arm chassis will be constructed. The advantages of IPMC in requiring low activation voltage and the induced large bending strain led to its consideration for various prosthetic applications. IPMC reacts to a changing voltage. When voltage is applied the material will bend, but if the voltage applied remains constant the material will slowly retract back to its neutral state. As the frequency of electrical impulses rises, so does the degree of fluctuation of the IPMC. Using this phenomenon of variation of degree of fluctuation with frequency of impulses, we can provide a 360 degree rotational arm by appropriately selecting the motor and impulse sequence. In major present prosthesis only vertical or horizontal movement of the prosthetic arm is possible. In this analysis, a rotational prosthetic arm using IPMC and controlled by nerve signal will be produced.
能够进行旋转运动的神经控制假肢的设计、开发和实现
假肢通常用于肢体丧失(获得性截肢)和肢体缺失(先天性缺陷)的人,以恢复或注入一些解剖肢体的功能和/或外观。假肢是生物机电领域的一部分,这是一门利用人体肌肉、骨骼和神经系统的机械装置来辅助或增强因创伤、疾病或缺陷而失去的运动控制的科学。离子聚合物-金属复合材料(IPMC)具有电致弯曲大、机械柔韧性好、激发电压低、密度低、易于制造等特点,是一种极具吸引力的电活性聚合物驱动材料。离子在电极间的扩散使材料弯曲。IPMC材料在义肢中充当人工肌肉。从自然受损肌肉获得的神经信号将被读取和放大,以便连接到失去肢体的IPMC将根据该信号的特征工作。电极将连接在病人的肢体和微处理器之间,微处理器将分析待处理的神经信号,并向IPMC提供适当的输出。一旦神经信号特征被读取并从IPMC得到反应,手臂底盘将被构建。IPMC在低激活电压和诱导大弯曲应变方面的优势使其在各种假肢应用中得到了考虑。IPMC对电压变化作出反应。当施加电压时,材料会弯曲,但如果施加的电压保持恒定,材料会慢慢缩回到中性状态。随着电脉冲频率的增加,IPMC的波动程度也随之增加。利用这种脉动度随脉冲频率变化的现象,通过适当选择电机和脉冲序列,我们可以提供一个360度的旋转臂。目前主要的义肢只能进行垂直或水平运动。在本分析中,我们将制作一个利用IPMC并由神经信号控制的旋转义肢。
