XL electrocardiograph and 58-size encephalograph

Contactless medical sensors have been createdDmitry Tselikov, Compulenta
Employees of the University of California at San Diego (USA) have proposed a medical sensor that can read information for an electrocardiogram or electroencephalogram through clothing, without skin contact.

As you know, for the current sensors that record changes in polarity in the human body, contact with the body and a gel pad are necessary. "Dry" sensors are inconvenient and very sensitive to extraneous movements.

Abandoning the electrodes, American researchers have created a capacitive sensor that conducts weaker signals, but does it at a short distance. The idea is not new, but attempts to develop such devices remained impractical for mass production – either too expensive or too sensitive to external noise. The sensor developed by bioengineer Gert Kauwenbergs and his graduate student Mike Chi (pictured) is devoid of these disadvantages.

Today, when cardiologists want to know how a patient's heart works for a long period of time, they send him home with a portable Holter ECG device that uses the same contact sticky electrodes. But this device can only be used for 48 hours, and incorrect heart rhythms cannot always be registered in such a short time. But Chi –Kauwenbergs sensors can be worn for as long as you want.

Together with the University of Oregon, scientists are working on a Bluetooth version of sensors (completely wireless) that will inform doctors about the patient's condition in real time.

In the distant future, the new technology may be useful for creating a human-computer interface. However, for this, the sensors must become more sensitive.
