A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

There are a number of linear motion technologies availableto machine and device designers, each with advantages and disadvantages.Medical device design in particular, in which applications typically ...

Piezoelectricity—the characteristic of certain solid materials whereby electric charge accumulates internally and is released when the material is stressed—was discovered by Jaques and Pierre Curie in ...

The integration of rotary and linear motions within a single actuation system has emerged as a transformative development in modern electromechanical engineering. Rotary-linear actuators combine the ...

Improvement in the design of medical equipment for better-streamlined functionality and performance is influenced by a number of critical factors. The research, design, modeling, testing, prototyping, ...

The earliest accounts of the manual wheelchair exist in documents from the sixth century. Surprisingly, the model used back then doesn’t look too much different than the one that wheelchair-bound ...

Just when you thought you had the “linear motion” concept nailed down – hit the required points on the straightaway and you’re home – along comes the remaining five degrees of freedom to crash the ...

Big, innovative breakthroughs often result in game-changing technologies. Smaller incremental improvements in essential material components can similarly lead to significant performance and efficiency ...
