Mindfield® eSense Pulse | optimal HRV Biofeedback

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 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).

 

Heart Rate Variability

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.

 

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.

 

Downloads of eSense Pulse

 

Download our eSense app

eSense app from Mindfield

Icon eSenseThe eSense comes with the eSense app which you can load for free in the in the Google Play Store (Android), in the Apple App Store (iOS) or the Amazon Appstore. 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 new: by light via a bluetooth smart bulb.

Procedures (inside the 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. 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 pulse will be recorded. Afterwards you see your results for each module and in total and you can export those to Excel for further analysis.

Kubios HRV Premium Software

Kubios

Many of our customers are interested in combining the eSense Pulse with the Kubios HRV Premium Software. This combination is suitable for scientific research as well as for the professional use as a biofeedback trainer. The Kubios HRV Premium Software offers you detailed HRV-analysis with its over 40 analysis parameters and can be perfectly combined with the eSense Pulse.

 

New: Magic Blue smart bulb (optional)

Magic Blue Bulb

The Magic Blue is a smart bulb which can be controlled via Bluetooth. The color as well as the brightness can be adjusted. This enables you to use the light from the bulb as an indicator of your level of stress or relaxation in combination with the eSense Skin Response or eSense Temperature.

From within the eSense App, you can connect to the Magic Blue and use it in your biofeedback session. Depending on the state of your relaxation, the bulb can show different colors or a different brightness or a combination of both.

You can purchase the Magic Blue here: https://mindfield-shop.com/en/magic-blue-led-esense.html.

Choose the Pulse for

Quick Guide to Usage

  • When you buy the eSense Pulse you can download our free app from the App Store (Apple®) or Google Play (Android).
    (You can also download it in advance, but the app can not be effectively used without the sensor)
  • Put on the chest strap as shown in the manual and adjust it to the correct length. The strap should be tight, directly under the chest muscles, but not uncomfortably tight or squeezed. 

  • Once you have adjusted the belt, remove it again to apply a small spray of the enclosed electrode contact spray to each electrode (but avoid 'bridging' as shown in the manual).
  • Start the app and click "Start", the measurements will begin.
  • Please carefully read the instructions within the app or the manual to get the best out of biofeedback training.
  • Have fun with the eSense Pulse!
