Abstract：To achieve uniform layered heating of subcutaneous dermal tissue at different depths by using a bipolar RF beauty de-vice,a time-sharing three gate mode dot matrix RF electrode array was designed.Firstly,the lattice was designed based on the rela-tionship between bipolar electrodes spacing and the heating depth.Under the different gating modes,the combination of bipolar elec-trode pairs with different spacing in RF circuits enabled the RF energy to reach the predetermined heating target position.After fixing the fresh pig skin that has been stripped of fat,the self-developed time-sharing three-way strobe dot matrix radio frequency beauty de-vice is used for heating experiment.Under the three gating modes,the working electrode spacings were 2.00,3.84 and 5.57 mm,re-spectively.The results indicated that three spacing electrode arrays,which acted on tissue with different subcutaneous depths,effective-ly expanding the heating area in sequence,and the uniform heating area reached 642 mm2 in the fully gated state.This can achieve uni-form layered heating of subcutaneous dermis tissue at different depths.
