CE Certified Frequently Asked Questions
What is biofeedback and how does it work?
Biofeedback is a technique that helps you learn to control your body's functions by measuring physiological signals like heart rate, skin conductance, or muscle tension in real-time. The eSense sensors connect to your smartphone and display these signals, allowing you to practice relaxation techniques and see their immediate effects on your body.
Which eSense sensor should I choose?
It depends on your goals: eSense Pulse measures heart rate variability (HRV) for cardiac coherence training. eSense Skin Response measures electrodermal activity (EDA) for stress awareness. eSense Temperature measures skin temperature for classic relaxation. eSense Muscle measures EMG for muscle tension training. eSense Respiration monitors breathing rate (add-on, requires Skin Response or Pulse).
Is the eSense app free? What devices are supported?
The eSense app is free to download with core biofeedback features included. It supports both iOS (iPhone, iPad) and Android smartphones and tablets. Some advanced features like cloud export, additional training programs, and music/video feedback are available as in-app purchases.
Are eSense sensors medical devices?
eSense sensors are CE-certified wellness and training devices, not medical devices. They are designed for personal stress management, relaxation training, and general well-being. They are not intended to diagnose, treat, cure, or prevent any disease. For medical conditions, please consult a healthcare professional.
How do I get started with biofeedback training?
Getting started is simple: 1) Choose your eSense sensor, 2) Download the free eSense app, 3) Connect the sensor to your smartphone, 4) Follow the guided training sessions in the app. Most users see their first results within the first session. Regular practice of 10-15 minutes daily is recommended for best results.
Can I use eSense sensors for professional therapy?
Yes, especially the eSense Muscle (Pro Edition) is designed for professional use in physiotherapy practices and rehabilitation centers. It includes a Web App for clinical workstations. All eSense sensors can be used by therapists as an affordable complement to professional biofeedback equipment.
What is the difference between biofeedback and neurofeedback?
Biofeedback measures peripheral body signals like heart rate, skin conductance, temperature, muscle tension, and breathing. Neurofeedback specifically measures brain activity (EEG). The eSense sensors are biofeedback devices. Mindfield also offers professional neurofeedback systems (MindMaster) for clinical use.
