Biofeedback with the eSense Temperature!
The eSense Temperature is a small sensor for measuring your skin temperature with the microphone input of your smartphone or tablet (Android or Apple iOS.)
Handwarming 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.
The eSense provides you in various ways with exact feedback about your momentary stress level, e.g. with measurement curves, video display and audio feedback features. The app for eSense is free, and allows exporting the measured data via e-mail.
For the audio features, the eSense has a headphone jack now. This means that additional to the auditory feedback you can listen to music or audio books while training your stress level down!
Systems:
• Apple® iPhone® (3GS and higher)
• Apple® iPad® (first generation and higher)
• Apple® iPod touch® (fourth generation and higher)
• Android Smartphones and Tablets (Version 2.3 or higher)
Your Android device needs a 3.5 mm input (standard headphone-type connector) for external microphones.
It's easy!
After buying the eSense Temperature, please download our free app from the App Store (Apple) or Google Play (Android). You can download and try out the app without the sensor. (The app will deliver meaningless values in this case.)
Hold the sensor between your index finger and thumb or fix it to a finger with the tape included.
Connect the eSense Temperature to the microphone input of your device.
Start the App, read the included instructions on biofeedback training and start using your eSense.
Skin temperature also depends on the environment temperature, so it is important to make measurements in consistently similar surroundings and to wait a few minutes before beginning training so that a steady "resting" temperature can be established.
Have fun!
Technical Data:
Measurement at 10 Hz (10 values per second).
One value per second (averaged) is stored in the app and can be exported as a CSV file via e-mail.
Resolution: 18bit, rounded to 2 digits after the decimal point. Not rounded for export to CSV.

Background information on Skin Temperature
The skin's surface temperature changes according to blood circulation through body tissue. The small blood vessels (arterioles) crossing through the tissue are surrounded by fibers of smooth muscle controlled by the sympathetic nervous system.
In a state of increased exertion, excitement and stress, these muscle fibers contract and narrow the blood vessels. This leads to a reduction of skin temperature because blood circulation through the tissue is reduced. By contrast, in a resting or calm state, the muscles relax and the blood vessels expand. The skin temperature rises.
Mental stress often leads to a lower peripheral perfusion and a decrease in skin temperature at the hands. From an evolutionary point of view, this stress reaction serves to prepare us to "fight or flight" in a physically threatening environment because a maximum amount of blood is concentrated in the working muscles.
Conscious control of physiological stress can help you react more relaxed and more efficiently to many situations. Biofeedback is an established way to learn this kind of control.
Reduce your stress level effectively with the eSense Skin Temperature everywhere with your Android or iOS device!
