☑ Complete heart rate variability statistics (time and rate data)

☑ Fast Fourier analysis in real time with spectrogram

☑ Breathing aid for breathing training with freely adjustable intervals, auxiliary tones and more

☑ Export of measurement data as a CSV file, compatible with other software programs for further analysis (eg Kubios)

☑ Export of curves, diagrams and statistics as a PDF report.

☑ Regular app updates

☑ Set any number of markers during a recording

☑ Several pre-made training methods are included in the app

☑ Free training according to your wishes with one or more variants of biofeedback

☑ Integration with our eSense Respiration to record respiration during measurement of HRV (Heart Rate Variability)

To train and improve HRV, the app provides a lot of feedback on HRV amplitude: Bar graph feedback (HRV or respiratory aid), Curve feedback (HRV and respiratory aid), Video feedback (included videos and your own videos can be used), Music feedback (included music can be used and your own music can be used), Tone feedback (pitch change by measured values), Tactile feedback by vibration (smartphones only, tablets cannot vibrate), Smart bulb feedback (Bluetooth®-bulbs and Philips Hue products).

Theoretically unlimited recording time (however, with some smartphones / tablets there are problems with storage of approximately 2 hours. Therefore, there is no guarantee for recordings of more than 120 minutes and under no circumstances are 24 hour measurements possible)

- An eSense Mindfield HRV Biofeedback pulse sensor

- One battery (for one year of use).

- A detailed instruction manual on biofeedback training to help you use our device

- Free Mindfield app through the App Store or Google Play

- You will also find a spray for the electrodes

- Extensive instructions for effective Biofeedback training

Heart rate variability biofeedback at home or on the go with iPhone or Android smartphone

                                      

  The Mindfield eSense Pulse is a small sensor to measure your heart rate variability with your smartphone or tablet (Android or Apple iOS).
 
The heartbeat is related to tension and relaxation and is a potential stress indicator. With the eSense Pulse you can measure and effectively reduce your stress level with biofeedback training. The eSense Pulse gives the user precise feedback about the current level of stress in a variety of forms, e.g. through measurement curves, video and audio presentation. With the eSense Pulse we have decided on a chest strap, which performs a 1-channel ECG measurement.
 
The eSense Pulse measures heart rate variability and, optionally with new eSense Respiration sensor, respiratory rhythm. The app belonging to the eSense is completely free of charge and also allows an export of the collected measurement data as CSV file or PDF report (eg via e-mail, Dropbox or Google Drive).

Measurement of heart rate variability at home (iPhone biofeedback at home)

Heart rate variability (HRV) refers to the ability to change the frequency of the heart rhythm.
 
Even at rest, there are spontaneous changes in the time between heartbeats.
A healthy person constantly adapts the heart rhythm to current requirements. In addition to physical exertion, such as sport or physical work, psychological exertion such as stress also results in an increase in the heart rate. The heart rate sinks again when the strain is relieved and the body relaxes. In humans, heart rate variability ranges from 10 (low, a sign of stress) to 30 (high, a sign of relaxation).
 
The more our body is able to regulate the heart rate (the greater the heart rate variability), the healthier we are. If the heart beats only rigidly, a person is about to die.
The measurement of heart rate variability is a large field in cardiology, sports and coaching and is used for extensive research. With the eSense Pulse, we want to focus on biofeedback training, i.e. improving heart rate variability. To describe the current state and progress of the training, the eSense app also provides the essential statistics and analyses of HRV.
 

Our hearts keep us alive and work tirelessly throughout our lives. It pumps the blood through our body, so that oxygen-rich blood penetrates all the parts of our body and oxygen-poor blood is enriched again in the lungs with fresh oxygen. But it also keeps everything moving, including the transport of nutrients, hormones, immune cells, etc.

It is easy to know that our heart is beating, you can feel your pulse or even hear it when you put one ear to the chest of another person. Since time immemorial, we have been studying and measuring the functions of the heart and measuring the heartbeat is essential.

Depending on the situation, our heart is able to regulate the heartbeat. When we sleep, it usually beats slowly and evenly, when we exercise, it beats fast and adjusts its frequency constantly. Depending on the creature, the resting pulse changes: only six heartbeats per minute for a blue whale and 1,000 heartbeats per minute for a shrew. We humans lie with approximately 60 heartbeats per minute in the lower range, infants have a faster resting pulse of approximately 130 beats per minute. With great effort, our heart can also beat at over 200 beats per minute.

Heart rate variability (HRV) refers to the ability to change the frequency of the heart rhythm. Even at rest, there are spontaneous changes in the time between heartbeats. Our body has a multitude of regulatory mechanisms to change the heart rhythm. Two essential components are the sympathetic nervous system, which activates and accelerates the heartbeat, and the parasympathetic nervous system, which acts as a brake to slow down the heartbeat.
A healthy person constantly adapts the heart rhythm to current requirements. In addition to physical exertion, such as sport or physical work, psychological exertion such as stress also results in an increase in the heart rate. The heart rate sinks again when the strain is relieved and the body relaxes. In humans, heart rate variability ranges from 10 (low, a sign of stress) to 30 (high, a sign of relaxation).
The more our body is able to regulate the heart rate (the greater the heart rate variability), the healthier we are. If the heart beats only rigidly, a person is about to die. The measurement of heart rate variability is a large field in cardiology and is used for extensive diagnostics. With the eSense Pulse, we want to focus on biofeedback training, i.e. improving heart rate variability. To describe the current state and progress of the training, the eSense app also provides the essential statistics and analyses of HRV.

Introduction to eSense Pulse

There are various methods for measuring the heartbeat. With the eSense Pulse, we have decided on a chest strap that performs a 1-channel ECG measurement. There are two electrodes in the chest strap which require good, direct skin contact. The chest strap must always be worn under clothing.
