Guide to FDA Requirements and Importance of Medical Device Calibration

Calibration of a device is carried out to minimize the uncertainty in measurements. It helps in reducing the errors and brings the measurement to an acceptable level....

In-Situ, Real-Time Monitoring of High-Power Lasers

A smaller, faster and more sensitive laser power meter in the form of a folding mirror uses a capacitor-based force transducer and merges optical elements, namely a high reflectivity mirror,...

New Reference Material Ensures Validity of Test Results

A new reference material is primarily intended for use in calibrating procedures and devices for the determination of C-reactive protein (CRP) in human serum. It can also be used for...

Toward Visible-Light-Based Imaging for Medical Devices

MIT researchers have developed a technique for recovering visual information from light that has scattered because of interactions with the environment — such as passing through human...

Bigger Isn't Better - How the Demand for Smaller, More Portable Medical Devices Is Driving Innovations in Sensor Technologies
