Vari-focal liquid microlens array using electrically responsive fluid actuated by ring array patterned electrode
A transparent fluid dibutyl adipate (DBA) is suitable for fabricating the adaptive lens
due to its unique deformation under a direct current (DC) electric field. In this report, a DBA
liquid microlens array (LMA) with tunable focal length is demonstrated. A hydrophobic layer
deposited in the ring-array patterns on the electrode induced the formation of the DBA liquid
microdroplets array self-assembly. The electronegative DBA liquid tends to move to the anode
at a DC voltage. The proposed DBA LMA with a diameter of 100 μm can change its focal
length from 0.92 mm to 1.42 mm when the voltage changes from 0 to 200 V. The response time
is relatively fast (~790 ms). Due to the high optical transmittance (~91%) and good thermal
stability in the temperature range of -24.8 -161.5℃, our DBA LMA shows good focusing
properties and has potential applications in the field of image processing, portable electronic
devices, beam steering, ophthalmology, and 3D displays.
