g.Sensors: Specs & Features

Sense the world! With g.tec's sensors for physiological and physical signals.

g.tec provides various sensors for physiological and physical signals. All sensors provide analog output signals, and are designed to be connected directly to the amplifier inputs or to the analog inputs of the data acquisition system. For safety reasons, all sensors, adapter cables and interface boxes are equipped with DIN 1.5-mm touchproof safety connectors.

20° C - 45° C
For skin temperature
accuracy: 0.2° C
The sensor is already
calibrated and provides an
output voltage of 0...200 mV
3-axes, +/- 3 g
acceleration sensor
Can be applied on the
subject's body or directly in a
simulator, vehicle or airplane to
monitor g-forces, acceleration and vibration
Respiration Effort
Piezo-electric crystal sensor in a robust belt system.
Can be used to record chest and abdominal
respiration waveforms independently.
Our respiration sensors connect
directly to amplifier inputs.
Respiration Airflow
This thermistor sensor is
placed in front of nose and mouth
and measures temperature changes in
inhaled and exhaled air. The resulting respiration
signal is very robust against movement artifacts.
Continuous Non-Invasive Blood Pressure Monitoring
g.CNAP is a world-leading system for non-invasive BP recording
and can be used as a stand-alone system as well. The analog
output signal (continuous BP in mmHg) can be
recorded with other parameters
and biosignals with g.tec systems.
Galvanic Skin Response (GSR)
Also called EDA (electro-dermal activity) or skin conductance.
Two small electrodes are used, preferably on the fingers
without any gel. The isolated circuit guarantees no
interference with other electrodes on the body.
Range: 0 - 30 µS,
1µS (micro MHO) calibration button.
snoring sensor for
sleep research. Picks
up tracheal sounds. To be
placed on the neck of the patient.
Limb Movements
This piezo-electric
sensor is placed on the
ankle to detect movements of
the feet during sleep. For investigation
of restless leg syndrome (RLS) and periodic
limb movements (PLM).

Oxygen Saturation
Two light sources with different wave
 lengths are used to measure the
 saturation of oxygen in the
 blood (SpO2). The sensor can be placed on the index finger.

A calibrated output signal is provided.

Compact and light-weighted
plethysmographic pulse sensor.
Finger transducer available.
Provides a clear analog pulse wave signal (e.g. to
be recorded together with ECG)
