MiniSense 100 Vibration Sensor
The MiniSense 100 is a low-cost cantilever-type vibration produces a linear output governed by the "baseline"
sensor loaded by a mass to offer high sensitivity at low sensitivity. The sensitivity at resonance is significantly

are solderable. Horizontal and vertical mounting options will excite the resonance fre-quency, as shown in the plot
are offered. The active sensor area is shielded for above (response of MiniSense 100 to a single half-sine
improved RFI/EMI rejection. Rugged, flexible PVDF impulse at 100 Hz, of amplitude 0.9 g). The ability of the
sensing element withstands high shock overload. Sensor sensor to detect low frequency motion is strongly

described below
The mass may be modified to obtain alternative frequency (see "Electrical
response and sensitivity selection (consult factory). Description").
The MiniSense 100 acts as a cantilever-beam
accelerometer. When the beam is mounted horizontally,
acceleration in the vertical plane creates bending in the
beam, due to the inertia of the mass at the tip of the beam.
Strain in the beam creates a piezoelectric response, which
may be detected as a charge or voltage output across the
electrodes of the sensor.
The sensor may be used to detect either continuous or
impulsive vibration or impacts. For excitation frequencies
below the resonant frequency of the sensor, the device
Outline Mechanical Dimensions
Electrical Description
The Minisense 100 behaves electrically as an "active" capacitor: it may be modelled as a perfect voltage source (voltage
proportional to applied acceleration) in series with the quoted device capacitance. Any external input or load resistance
will form a high-pass filter, with a roll-off frequency as tabulated above, or calculated from the formula f(c) = 1/(2 RC).
The impedance of the sensor is approximately 650 M ohm at 1 Hz. The active sensor element is electrically shielded,
although care should be taken in the PCB design to keep unshielded traces as short as possible.
