Until about 10 years ago, the force test and measurement industry had been fairly unimaginative. It had developed a standard way of building analog load cells, torque transducers and other devices, ...

Cells exert, sense, and respond to physical forces through an astounding diversity of mechanisms. Here we review recently developed tools to quantify the forces generated by cells. We first review ...

Although a power supply and a DMM are fine for some measurements, there are many advantages to having sourcing and measuring in the same instrument. Yet many engineers I encounter are not familiar ...
