MEMS (Micro Electro-Mechanical System), is a chip-based technology which contains a microscopic mechanical structure inside. MEMS sensors can be used to measure physical parameters such as acceleration.

The most prominent feature of MEMS technology is their miniaturized dimensions. They are small, lightweight and reliable. MEMS technology gives high-sensitivity output and it provides us with ease of integration. DynaLabs MEMS sensors can measure low frequencies such as 0 Hz.

Capacitive MEMs accelerometers, also known as vibration sensors, are small, lightweight and have a DC response. A capacitive accelerometer measures the acceleration on a surface using capacitive sensing techniques. DynaLabs Capacitive accelerometers convert capacitance change into voltage. MEMS-based capacitive accelerometers provide accurate vibration measurements in performance-driven applications. Capacitive accelerometers have excellent long-term stability and reliability and work well at low frequencies.

Dynalabs Capacitive accelerometers have 2 types: Uniaxial (1000 Series) and triaxial (3000 Series). They have 3 different groups within themselves: LN, DE and SE series.

                 

 

A single-ended (SE) measurement is taken as the voltage difference between a wire and ground. The noise is only on the positive wire and is consequently measured together with the output voltage from the sensor. These sensors also have a positive bias voltage.

DE series accelerometers are Differential Ended sensors. A differential voltage has no reference to ground. The measurement is taken as the voltage difference between the two wires(+) and (-). The main benefit of a differential measurement (DE)  is noise rejection, because the noise is added to both wires and can then be filtered out by the common mode rejection of the data acquisition system. Furthermore, there is almost no bias voltage.

LN series accelerometers are Low Noise version of Differential Ended sensors.

 

Piezoresistive sensors are also MEMS sensors. The sensing  material is piezoresistors which change resistivity according to the acceleration. Piezoresistive MEMS accelerometers are usually low sensitivity devices used in shock and drop testing applications. Piezoresistive sensors are used in high impact and shock applications with very high accelerations from ±100 g to ±6000 g.

Dynalabs Piezoresistive accelerometers have 2 types: Uniaxial (4000 Series) and triaxial (5000 Series).

MEMS Gyroscopes are used whenever angular velocity sensing (°/s) is required. MEMS gyroscopes operate with high precision. They do not have rotating parts that require bearings and this allows an easy miniaturization.

DynaLabs Gyroscopes have 2 types: Uniaxial (6000 Series) and triaxial (7000 Series).

IMU is a sensor that collects angular velocity and linear acceleration data in a single module. The IMU’s mission is to determine the speed and angle of rotation of the device or vehicle.

Dynalabs IMUs are based on triaxial accelerometers and triaxial gyroscopes that are integrated in a single housing. Any combination of gyroscopes and accelerometers is possible.

Dynalabs IMUs enable separate analog voltage outputs for all 6 degrees of freedom (DOF).
