Abstract

The invention provides a lie detection device and method. The lie detection device comprises an electronic stethoscope, a processor, a storage and a wireless signal transceiver, wherein the electronicstethoscope is attached to the chest of a detected object to acquire current heartbeat data of the detected object and transmit the heartbeat data to the processor, the storage stores computer programs runnable by the processor, the heartbeat data of the detected object under normal conditions and heartbeat data of sample people under the normal conditions, the processor is used for judging whether the detected object lies or not currently, and judgment results are transmitted to an external terminal device by the wireless signal transceiver and displayed. Compared with the prior art, the liedetection device has the advantage that the light and portable lie detection device can be formed only by the electronic stethoscope with a small size, the processor, the storage and the wireless signal transceiver.

Description

technical field [0001] The invention relates to the technical field of lie detection, in particular to a lie detection device and method. Background technique [0002] Polygraph detection is an activity to identify lies, and it is widely used in human activities such as police cracking cases, investigating cases, and entertainment activities. In the prior art, polygraph generally adopts polygraph to detect polygraph, and polygraph is a kind of scientific instrument for recording various physiological changes (respiration, pulse, frequency, blood pressure and skin humidity etc.) of people when mood changes. The principle of lie detection is: when most people tell a lie, their emotional fluctuations will lead to a series of changes in the activity of the autonomic nervous system, which in turn will cause changes in physical signs, such as increased breathing and swallowing frequency, increased sweating, and increased heartbeat. etc. These are all involuntary and difficult to ...
