They say to make an omelet you need to break a few eggs. Of course, it helps when the eggs are broken into the bowl, and not broken in the carton prior to taking them out.
With advancements in prosthetics allowing fine motor control driven by a patient's nervous systems, the use of miniature load cells placed at grip points helps observe a wide variety of operating conditions the patient requires from their prosthetic every day.
A load cell has to meet many requirements to be fit for use in a robotic prosthetic:
FUTEK mini load button LLB130.
FUTEK's miniature button load cells (LLB130) meet and exceed the requirements for sensors in robotic prosthetics. The sensors are 9.5 mm in diameter and 3.3 mm thick. They come in a variety of capacities, including 10-lb and 25-lb models that are perfect for measuring loads similar to that of human fingers. All feature a non-repeatability of 0.1 percent, an operating temperature range of -51 deg C to 93 deg C, and a 17-4 PH stainless steel housing to handle a wide range of environmental conditions.

Finally, given the varying labs and test environments that robotic prosthetics are tested in, flexibility and ease of interface to lab computers is essential. Here, FUTEK's miniature button load cells interface with not only PLCs, but also FUTEK's USB 24-bit interface kits paired with their SENSIT Test and Measurement Software for live logging and graphing on a PC.
