Vitalérzékelés

Vitalérzékelés, also known as vital sensing or life signal detection, refers to the technology and methods used to detect the presence and movement of living beings. This field encompasses a variety of techniques, often employing different types of sensors to identify physiological or physical indicators of life.

One common approach utilizes radar technology. Doppler radar, for example, can detect the subtle movements associated with breathing and heartbeat, even through obstacles. Infrared sensors are also employed, as living organisms emit heat, making them detectable in thermal imaging. Pressure sensors can identify the weight of a person or animal on a surface, while acoustic sensors can pick up sounds like voices or footsteps.

The applications of vitalérzékelés are diverse. In search and rescue operations, it can help locate individuals trapped in rubble or beneath snow. It is also used in security systems to detect intruders, in healthcare for non-contact patient monitoring, and in automotive safety systems to detect occupants. The development of more sensitive and versatile vitalérzékelés technologies continues, aiming to improve accuracy, range, and the ability to distinguish between different types of life signs.
