Human body conductivity

Human body conductivity (car+light strip) - customized science museum exhibitions, campus community science popularization equipment, source manufacturer of science exhibitions description and scientific principle introduction:

Exhibition items use interactive experiences to treat the human body as a part of an electrical circuit, forming a loop that enables corresponding appliances or electric toys to operate. This allows the audience to understand the relevant principles of human conductivity. Exhibition items mainly consist of a platform, protective devices, drive systems, and starting devices. Display items: Set up a table with a circular area in the middle, with a built-in drive system and operating device forming a disconnected circuit. When the audience places both hands on the touchpad, the circuit will be disconnected. Due to the conductivity of the human body, a circuit is formed, so the built-in car begins to run in a circular shape along the track.

Main technical parameters of exhibits:
