AI Technical Summary
In the medical field, active medical devices inside the human body are susceptible to electromagnetic waves, causing their normal work to be threatened, which in turn endangeres the health of patients.
A temperature-adjustable medical electromagnetic shielding composite material is used, which includes CF/ASA electromagnetic shielding composite material, graphene and RGO@NiFe2O4 surface absorbing coating, three-dimensional Ti3C2MXene electromagnetic shielding composite material, magnetic field sensor, temperature sensor and signal processing unit and gallium-based liquid metal. Gallium-based liquid metal is filled in the cavity of the three-dimensional Ti3C2MXene electromagnetic shielding composite material, and the spatial arrangement of gallium-based liquid metal is adjusted by using magnetic field sensors and temperature sensors to achieve the shielding and temperature control of electromagnetic waves.
The composite material has excellent electromagnetic shielding function, which can effectively prevent the impact of electromagnetic waves on medical devices. By adjusting the distribution of temperature sensors and magnetic field sensors, the ambient temperature is controlled to ensure the stable operation of medical devices under different temperature conditions.
