Mindfield® eSense Pulse | optimal HRV Biofeedback

 

HRV Biofeedback with the eSense Pulse!

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 HRV 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. Determine your HRV biofeedback easily and anywhere and optimise your health.

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).

 

Measure heart rate variability and optimise HRV biofeedback

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. With HRV biofeedback through the eSense Pulse, you train your heart muscles in a playful way and thus promote your health day after day.

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 HRV 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. Measuring heart rate variability regularly is enormously important for competitive and amateur athletes. It can significantly improve your athletic performance in terms of endurance and resilience. The eSense Pulse gives you unique insights into your HRV biofeedback and thus into your cardiovascular performance. HRV biofeedback training can give you a strong competitive edge in sports.

Heart Rate Variability and Biofeedback Training

The aim of HRV biofeedback is to increase heart rate variability, specifically its amplitude. In other words, to maximize the difference between low heart rhythm and high heart rhythm in the interplay of inhalation and exhalation, rest and demands.

If respiration is included, the eSense App offers various ways to visualize it and to define respiration in a certain rhythm. The coupling of heartbeat and respiration is greatest in most people when breathing at about 4.5 to 6.5 breaths per minute. Observing by measuring these variables is what makes HRV biofeedback possible in the first place, so that heart rate variability (HRV) can be increased bit by bit. This biofeedback training is a promising method to improve your heart health and increase athletic performance. The eSense Pulse gives you detailed insight into how successful you are in controlling your heart rate variability during each training session.

eSense Mobile App

Icon eSenseThe eSense comes with the eSense app which you can load for free in the in the Google Play Store (Android) or in the Apple App Store (iOS). The app contains a variety of functions for an effective biofeedback training in a modern design. Essential function are the display of the measured values app as bargraph and oscilloscope, a feedback by video, music, tones, vibration and by light via a Bluetooth® smart bulb.

 

eSense Web App and SDK

In addition to the app, we have also developed an eSense web app that mirrors and supplements the app. You can use this with the account and plans mentioned above. You can analyze your recorded data (with the basic plan) or even transfer your data to a PC in real time (live streaming with the premium plan).

The main advantage of this is that you can see the graph even better with a large screen and enlarge individual areas and have more advanced analyze features.

You can also create your own apps with our SDK. We have also developed the eSense Web App which allows you to stream your measurement data directly to a PC.

 

eSense Pulse & eSense Respiration

The eSense Pulse can be combined with the eSense Respiration and used simultaneously. Your breathing is a stimulator for your heartbeat and therefore combining both eSense sensors can take your training to the next level.

 

Procedures (inside eSense App)

A Procedure consists of several assembled modules. A module can be for example a picture, a video, some music, a bargraph, an arrow or others. You can assemble the modules in any length to a fixed procedure. Some contain biofeedback-functions (that means they reflect the changes in your measured values from the eSense), some don’t.

Procedure Archive English

With this feature you can build the perfect individual relaxation guide, a stress test, a predefined biofeedback training or use it for your own research. There are many possibilities. During a procedure, your skin response, respectively or temperature (depending on the eSense sensor you have) will be recorded. Afterwards you see your results for each module and in total and you can export those to Excel for further analysis.
