Computer-aided rehabilitation engineering--CARE.

Abstract

Computer-aided design (CAD) and related technologies are having a dramatic impact upon manufacturing industry. The advantages of these technologies over traditional methods include improved accuracy and quality, reduced product development time and ease of product modification and hence customization. The resultant increases in productivity, whilst maintaining flexibility of design, have obvious potential in the rehabilitation equipment industry. Recent applications of these technologies to the analysis of prostheses and wheelchairs and to the design and production of sockets for amputees, prosthetic implants and custom seating are reviewed. Computer-Aided Rehabilitation Engineering (CARE) is in its infancy. However, given the rapidity of developments in this field, CARE has the potential to radically alter rehabilitation engineering over the next decade.

Optimal design of non-Newtonian, micro-scale viscous pumps for biomedical devices.

The present paper addresses the numerical optimization of geometrical parameters of non-Newtonian micro-scale viscous pumps for biomedical devices. The objective is to maximize the mass flow rate per unit of shaft power consumed by the rotor when an external pressure load is applied along the channel that houses the rotor. Two geometric parameters are considered in the optimization process: (i) the height of the channel that houses the rotor (H) and (ii), the eccentricity (epsilon) of the rotor. Three different micro-scale viscous pump configurations were tested: a straight-housed pump (I-shaped housing) and two curved housed pumps (L- and U-shaped housings). The stress-strain constitutive law is modeled by a power-law relation. The results show that the geometric optimization of micro-scale viscous pumps is critical since the mass flow rate propelled by the rotor is highly dependent on epsilon and H. Numerical simulations indicate that mass flow rate is maximized when epsilon approximately 0, namely when the rotor is placed at a distance of 0.05 radii from the lower wall. The results also show that micro-scale viscous pumps with curved housing provide higher mass flow rate per unit of shaft power consumed when compared with straight-housed pumps. The results are presented in terms optimized dimensions of all three configurations (i.e., H(opt) and epsilon(opt)) and for values of the power-law index varying between 0.5 (shear thinning fluids) and 1.5 (shear-thickening fluids).
