Mindfield eSense Skin Response, eSense Temperature, eSense Pulse & eSense Respiration

Biofeedback with the eSense sensors!

You can buy four eSense sensors from our shop:

1. the eSense Skin Response to measure electro dermal activity or galvanic skin response (EDA, GSR)

The Mindfield eSense Skin Response is a small sensor to measure your skin conductance using the microphone input of your smartphone or tablet.
Your skin conductance depends directly on your state of relaxation or stress, making it a commonly used and very precise stress indicator.
With the eSense Skin Response, you can precisely identify your stress level and reduce it with biofeedback training.
This App includes a comprehensive manual for training and many training possibilities.

2. the eSense Temperature:

The eSense Temperature is a small sensor for measuring your skin temperature with the microphone input of your smartphone or tablet.
Hand warming training is an especially effective and common biofeedback method. The temperature of our hands is connected to our stress level:
When we are stressed, we tend to have cold hands. Immediate feedback enables you to voluntarily increase the skin temperature in your fingers,
thus, increasing your peripheral blood circulation, leading to relaxation and stress reduction.

3. the eSense Pulse:

The Mindfield eSense Pulse is a precise 1-channel ECG chestbelt sensor to measure your heart rate variability with your smartphone or tablet.
The connection is made via bluetooth. The heartbeat is related to tension and relaxation and is a potential stress indicator.
The measurement of heart rate variability is a large field in cardiology, sports and coaching.
With the eSense Pulse, we focus on biofeedback training, i.e. improving heart rate variability to reduce your stress level.
The eSense app also provides essential statistics and analyses of HRV.

4. the eSense Respiration:

The new eSense Respiration sensor measures breathing amplitude and frequency with a pressure sensor and flexible belt and,
optionally with eSense Pulse sensor, Heart rate variability alltogether simultaneously.
It provides a unique and rich biofeedback experience on your smartphone or tablet to learn or regain a healthy breathing pattern.


You need to buy an eSense sensor for this App, otherwise you cannot measure anything.

Great HRV Trainer

Love the HRV training program. Have found it very beneficial for dealing with my stress and teaching others to deal with theirs.

Delighted to the new HRV sensor

I’ve used the Temperature and Skin
Conductance sensors with great success and am delighted to see the new HRV ( chest belt ) sensor arrive. I used it straight out of the box with no problems and got exactly the same sense of relaxation that I get from other HRV devices. App works well, and the equipment is very well priced. The statistics are professional level. Obviously there is some fine tuning to be done, but great so far. Once the respiration sensor arrives it will be a formidable set of equipment.

Needs some input from a designer

I am a biofeedback practitioner and recommended this app and its sensor regularly to my clients for home practice. It has been especially useful during the pandemic. I find the visual feedback to be very helpful. However, the audio feedback is poor, and the app feels clunky overall. Frankly, I can tell it was designed by engineers. Some work with a designer who can make it more appealing to the masses would be helpful. This is a great product, but it just needs some extra care.
