Self-calibrating MEMs to enable super-accurate sensors

Self-calibrating MEMs to enable super-accurate sensors: "Micro electromechanical systems, or MEMs, are promising in an array of high-tech applications. However, the accuracy of conventional techniques to gauge the force and movement of tiny objects containing components so small they have to be measured on the scale of micrometers or nanometers are typically off by 10 percent or more because of their inherent uncertainties. A new technology enabling MEMs to 'self-calibrate' could overcome this problem and make possible super-accurate and precise sensors for crime-scene forensics, environmental testing and medical diagnostics."
