|Applicants:||NAZHIYUAN TECHNOLOGY (TANGSHAN), LLC
|Title:||TRIBOELECTRIC SENSOR TESTING DEVICE SIMULATING VITAL SIGN|
A triboelectric sensor testing device (100) simulating a vital sign , the device comprising: a first frame (101); a sample table (102) and a first airbag (103) provided on the first frame (101), wherein an accommodating space is formed between the sample table (102) and the first airbag (103), and a triboelectric sensor (109) can be disposed in the accommodating space; and an air drive unit (105) connected to the first air bag (103). The air drive unit (105) is configured to repeatedly increase or decrease the amount of air in the first air bag (103), such that two contact surfaces of the triboelectric sensor (109) can come in contact or separate from each other, providing the triboelectric sensor (109) with a test condition close to a vital sign.
