The critical dimensions of MEMS devices can vary from well below one micron, onthe lower end of the dimensional spectrum, up to several millimeters. The competitive MEMS-based accelerometer models for severe shock , with ranges of 20,000 G or above, are listed in the first two filled columns of TABLE 1 below.

PCB & Endevco variable capacitance accelerometers incorporate MEMS technology to provide accurate measurements in lightweight packaging. We offer both single axis and triaxial options for a variety of industries and applications.

When coupled with microelectronic circuits, MEMS sensors can be used to measure physical parameters such as acceleration. Unlike ICP® sensors, MEMS sensors measure frequencies down to 0 Hz (static or DC acceleration). PCB® manufactures two types of MEMS accelerometers: variable capacitive and piezoresistive.

In Verbindung mit mikroelektronischen Schaltungen können MEMS-Sensoren zur Messung physikalischer Parameter wie z. B. der Beschleunigung eingesetzt werden. Im Gegensatz zu ICP®-Sensoren messen MEMS-Sensoren Frequenzen bis zu 0 Hz (statische oder DC-Beschleunigung).

We find that piezoelectric sensors outperform MEMS accelerometers in terms of frequency range for early detection, making them the preferred option for machine health monitoring applications.

While MEMS may be easy to integrate to the electronics of a wireless radio or personal activity monitor, it can be very difficult to integrate a MEMS chip into the mechanical packaging of a sensor and achieve the vibration coupling necessary for early detection of bearing or gearing faults.

The micro-electromechanical systems (MEMS) sensor incorporates sufficient squeeze-film damping to reduce resonant amplification during violent events by orders of magnitude over conventional

The MEMS device described in this paper was intentionally designed with a relatively low resonant frequency. This provides natural filtering, that is, attenuation of frequency components above the resonance, and also allows sufficient displacement of the inertial seismic mass so that it is possible to incorporate squeeze film damping.

In contrast, MEMS are mainly of two types: piezoresistive , used for tests at high acceleration values such as impacts and shocks ; and capacitive, which can sometimes also be used in these types of dynamic measurements characterized by limited acceleration values.

Piezoresistive accelerometers may be fabricated from metal strain gauges, piezoresistive silicon, or as a MEMS device. In such designs resistive material is typically bonded to a cantilever beam that undergoes bending under the influence of acceleration.

VC MEMS accelerometers are built with gas-damping mechanisms and internal over-range stops that protect them from high shock levels and vibration, making them ideal for environments where rapid changes in mechanical stress are common.
