Fields of research

GT3X+ activity monitors (ActiGraphTM) for recording physical/sporting activity. In addition to the three-dimensional recording of movement activity and body position, the devices also allow the measurement of lighting intensity in lux, which means they can also be used in sleep research. We use these devices to investigate the relationship between physical activity and psychosocial factors over a period of several days/weeks.

The EcgMove 4 from movisens (movisens GmbH) is a mobile sensor for determining the ECG signal in combination with physical activity. The combination of these two parameters makes it possible to draw conclusions about the behavior, activity and functionality of the heart and the autonomic nervous system in just a few steps.

Applications:

• Interactive ambulatory assessment
• Mobile long-term monitoring of heart rate and heart rate variability
• Examination of the autonomic nervous system
• Behavioral monitoring
• Psycho-physiological stress monitoring
• Energy expenditure estimation and activity recognition
• Affective computing
• Integration into complex systems

eMotion Faros is a mobile ECG recorder for monitoring ECG, heart rate variability (HRV), stress, recovery and general well-being, suitable for short-term and long-term measurements.

FUNCTIONS:

• offline and online ECG recording
• ECG sampling rate up to 1000Hz
• Activity tracking (3D acceleration, sampling rate up to 400Hz)
• ADC accuracy: 14 bit
• Bluetooth, range up to 10 meters
• Storage capacity: 20-30 days of recordings
• Charging time: approx. 1 hour
• micro-USB download

Equivital^TM EQ-01 Sensor Unit (Hidalgo Limited), consisting of a chest strap fitted with various sensors and an electronic processing and memory module (SEM). We use these devices to record the ECG via two leads, respiration (depth and frequency), skin temperature and movement activity and body position (using integrated three-dimensional acceleration sensors). We use these devices for outpatient data acquisition over several days.

The medilog® AR12plus long-term ECG recorder can be used for either 1 or 3 ECG channels and offers a wide range of options for comprehensive ECG analysis.

FUNCTIONS:

• PureECG technology
• HRV analysis
• Apnoea detection
• ST/QT/pacemaker analysis
• QRS detection
• P-wave detection and atrial analysis
• Motion sensor
• Wireless BluetoothTM interface
• SpO2 sensor (optional)
• Up to 80 hours recording time
• Water repellent

MEMS® Cap records the date and time of up to 4,000 dosing events (open/close). Stored information is transferred to the medAmigo Software Suite for analysis and interpretation using the MEMS® Reader.

FUNCTIONS:

• Waterproof
• Wireless data transfer via NFC communication
• Non-volatile memory

VarioPort devices (Becker Meditec) for recording various physiological signals in the field and laboratory. We primarily use these devices to record the long-term ECG over 1-3 days, movement activity and body position (using one- and three-dimensional acceleration sensors) as well as speech activity. The VarioPort devices allow the recording of up to 16 analog channels with a resolution of 16 bits and a global scan rate of 512 Hz and therefore offer a high degree of flexibility for different examination approaches.
