Page 6: Skin Response In General
The eSense Skin Response applies a very small, safe and unnoticeable electrical voltage, which results in an electrical current to the skin. Through the changes of this small current, we can measure the activity of the perspiration glands of the skin far below the threshold of self-perception. -
Page 7: Skin Response And Biofeedback Training
If you suffer from a serious disorder or medical condition, always consult a professional physician or therapist, and do not attempt to treat yourself. The eSense Skin Response is not a medical device and may only be used for stress reduction training. -
Page 8: Skin Conductance Response (Scr)
Or are you “stressed” because you are full of drive and are excited? In both cases, the eSense Skin Response shows elevated values. However, in the first case, this is to be judged negatively. In the second case, you can simply enjoy and use the active or euphoric state. - Page 9 We have colored the SRC/min in the eSense app. Low SRC are green or yellow and high SRC/min are orange or red. While making a measurement, the recognized SRC colored within curve. examples from app: Example of a measurement in a relaxed state with little SRC/min (green and yellow) Example of a measurement in a stressed state with more SRC/min (yellow and orange)
- Page 10 In the right diagram, there is also the time in which the values rise, fall or have been steady. With rising stress, the curve rises more often and longer than it keeps steady or falls. This is also an ideal parameter to analyze and to compare biofeedback sessions.

Page 12: Preparation And Start Of The App
Using the non-dominant hand is advisable (e.g. the left hand for right handed people) because the skin tends to be a little less callused there. Attach the cables and wrap the tape another time around their clips to ensure a firm contact. eSense Skin Response in use with a tablet... - Page 13 If the conductance is permanently bad, we have listed several tips in the FAQ for the eSense Skin Response to improve the conductance. Usually gel electrodes are necessary. Don’t continue with the training if the values are below 1µS and solve the cause first.

Page 14: Procedures
Procedures A procedure consists of several assembled modules. With this new feature, you can build the perfect individual relaxation guide, do a stress test, use it for pre-defined biofeedback training or use it for research. There are many possibilities. During a procedure, your skin response or temperature (depending on the eSense sensor you have) will be recorded, and after the recording is made, you can see your results for each module and in total. -
Page 15: Preparation And Start
Preparation and start 1. Follow the first steps of preparation from the previous chapter and choose an open training in the selection screen after starting the app 2. Tap on Start and have a first look at the measured values 3. -
Page 16: First Stage (Observe And Experiment; Determine Your Initial Status)
Example of a phase with relaxation First stage (observe and experiment; determine your initial status) 1. Record your baseline state for ten minutes at rest without influencing the measurement. Relax as best as you can and do NOT watch the measured values for the whole ten minutes, as it would compromise a true baseline measurement. - Page 17 Example of a measurement curve (after 5 minutes duration the background is colored) 3. After completing the ten-minute baseline, you will be shown a survey first. Answer the questions and take notes if necessary. Then you'll see the pie charts that show you the fluctuations per minute (in the best case, everything is green) and how often the readings have risen, stayed the same, and dropped.

Page 18: Second Stage (Targeted Biofeedback Training With The Skin Response)
Second stage (targeted Biofeedback training with the skin response) 1. The second stage consists of multiple sessions. These sessions should always follow the following scheme. You shall now exercise conscious relaxation with the feedback signal. 2. Start the measurement and watch the values for a while. Then try to bring them down through active, conscious intervention. -
Page 19: Fourth Stage (Transfer; Relaxation Without Feedback)
or situations that distress themself. For example, if you have trouble speaking out loud before a larger group of people, try to imagine the situation and hold a speech before them. Under the influence of such a stressor, you are likely to see a surge in skin response. -

Meditations You can also choose one of our guided meditations as a procedure. The breathing meditation is already included in the eSense app. We will also offer more meditations shortly as new free cloud procedures for users with account. The meditations thus offer you an easy way to train your awareness and attention and, at the same time, receive biofeedback. -
Page 33: Settings (Overview)
Settings (Overview) Feedback Direction Select the direction in which you want the feedback to react to. It can respond either to an increase or decrease in the measured values. Response time The default setting is "Short", which allows feedback to respond quickly to changes in readings. - Page 34 Tactile Feedback Your device will vibrate to provide feedback. Only smartphones support this feature, tablets do not have a vibration motor. Tactile feedback direction Decide whether decreasing ("Decrease") or increasing ("Increase") tactile feedback values should be considered a success. Smart bulb feedback The light bulb changes its color depending on the values.

Page 41: Account And Cloud
Account and Cloud You can register your own, free account for the eSense app and book plans. You can also benefit from free, regularly added procedures without booking a plan. Thus, we recommend using the app with an account. With the plans you can mainly use the cloud and its functions and get also access to the eSense web app. -
Page 42: Esense Web App
eSense Web App 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). -
Page 43: Supported Devices Android
Supported devices Android In general, Android smartphones and tablets from Android 7.0 (Nougat) can be used with the eSense without complications. Your Android device requires a 3.5mm jack (headphone jack) for external microphones. Most devices have a headphone jack built into them by default. We suggest you use the affordable Nokia 2.3 as a smartphone with the eSense. -
Page 44: Smart Bulb (Optional)
Lightning to 3.5 mm Headphone Jack Adapter Smart Bulb (optional) eSense Skin response in use with the Magic Blue smart bulb The eSense app can support biofeedback via smart bulbs. Smart bulbs can change their colors and brightness and can be controlled via Bluetooth. In combination with the eSense app, smart bulbs indicate your level of stress or relaxation through their lights. - Page 45 From within the eSense App, you can connect to the Magic Blue or the Phillips Hue and use it in your biofeedback session. We have more information about the smart bulbs in our FAQ: https://www.mindfield.de/dwnld.php/?download=161 Magic Blue You can buy the Magic Bulb at our shop at https://mindfield-shop.com/en/magic-blue-...

Page 48: Possible Electrode Positions
Possible electrode positions General information for the skin preparation (independent from the electrode type): Skin preparation or skin cleansing is usually not necessary and also not recommended. It is enough to wash the hands, although the soap dries the skin and lowers the measured values. -
Page 49: Gel Electrodes
Gel electrodes We recommend the single-use gel electrodes. There are three different possibilities of the areas of conduction, as shown in the images. All positions are equivalent. Simply connect the electrodes wire through the press button connectors with the electrodes. Finger clips These EDA finger clips are simply put on the fingertips of the index and middle finger. -
Page 50: Eda Gel Electrodes
