EMBEL: Research Fields
Personal and body area electronics
We make electronics
disappear, embedding it
into your clothes and bed,
under the skin,
into your body and organs –
lungs, heart, brain, etc...
and helping so your healing
and making your life more enjoyable
when your body organs
are injured or weary of life

EMBEL: Research Fields
Body area sensor network
•
BAN – Body Area Network
•
PAN – Personal Area Network
•
Conductive communication
through tissue as via “liquid wire”
•
Near-field wireless communications (400 MHz, MICS)

Impedance of the communication media (body) against
the electromagnetic field
characterizes properties of
the body

Tissue impedance exposes as
a biosensing parameter

BME: Research Fields
TensioTrace – Device for continuous beatto-beat blood pressure measurements.
The theoretical background of the method
based on study results of Department of
Biomedical Engineering and Estonian
Institute of Cardiology.
Advances of the method:
1) Simple measurement procedure;
2) Short measurement time (output for every
heart beat);
3) Fully non-invasive and patient-friendly
method (because we use light).


Brain research:
understanding and protection of
the brain

Interpretation of the EEG signal:
• New methods of EEG analysis sensitive
to reveal small alterations in the signal
hidden in natural variability of the EEG;
• Effect of modulated microwave radiation
on the brain – harmful or healing;
• EEG-based parameters for distinction of
alterations characteristic for mental
disorder (depression)


Prediction of sudden cardiac death (SD)




European Union - 3000 cases per day/1,1 million per
year
USA – 1500 cases per day/500 000 per year
Professional help is still possible during the first 4-5
min after SD appearance
Prediction is important!
• Parameters: Non-invasive VR parameters, physiological,
biochemical and radioimmunological investigations and assessing
QT interval parameters
