g.Sensors: Specs & Features

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.

Temperature 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			Acceleration 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 Piezo-electric 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.			Pulse 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)
