Abstract: Disclosed are methods and systems for testing electronic devices for leak detection, wherein the test does not destroy the electronic devices. In one method of detecting a leak in a sealed package, a sealed package is placed in a test gas environment, thereby allowing the test gas to diffuse into an internal space of the sealed package through a leak formed in the sealed package. Thereafter, the sealed package is placed in an environment substantially free of the test gas and allowing the test gas to diffuse out of the internal space. The amount of the test gas in the test gas-free environment is detected. Based on the information obtained from the detection, it is determined whether the sealed package has one or more unintended leaks based on information obtained from the detecting.

Abstract: Embodiments of the present invention are directed to a MEM viscosity sensor that is configured to be operated submerged in a liquid. The MEMS viscosity sensor comprises a MEMS variable capacitor comprising a plurality of capacitor plates capable of being submerged in a liquid. An actuator places a driving force on the variable capacitor which causes relative movement between the plates, where the movement creates a shear force between each moving plate and the liquid, which damps the movement of the plate and increases the capacitor's response time to the applied force in accordance with the liquid's viscosity. To determine the actual viscosity of the liquid, a sensor is coupled to the variable capacitor for sensing the response time of the plates as an indicator of the liquid's viscosity.

Abstract: This invention relates to a liquid measurement cell for micromechanical sensors, so-called cantilever sensors. These sensors are e.g. used for the detection of biomolecules without the need for fluorescent or radioactive labelling. These measurements are usually carried out in liquids, where air or gas bubbles present in the analyte inside the measurement cell can significantly affect measurement results or even destroy the sensor. In a measurement cell according to this invention, a closed gas volume is present above the liquid level. Consequently, gas or air bubble can be constantly absorbed by the gas volume and do not come in contact with the cantilever sensors. The measurement cell is further characterised by a very low volume in the order of microliters and can be combined with various optical or piezoelectrical/piezoresistive read-out methods.
