Abstract
Inflatable
conducting devices providing improved properties and functionalities are needed
for diverse applications. However, the difficult part in making
high-performance inflatable devices is the enabling of two-dimensional (2D)
buckles with controlled structures on inflatable catheters. Here, we report the
fabrication of highly inflatable devices with controllable structures by
wrapping the super-aligned carbon nanotube sheet (SACNS) on the pre-inflated
catheter. The resulting structure exhibits unique 2D buckled structures
including quasi-parallel buckles, crisscrossed buckles, and hierarchically
buckled structures, which enables reversible structural changes of 7470%
volumetric strain. The 2D SACNS buckled structures show stable electrical
conductance and surface wettability during large strain inflation/deflation
cycles. Inflatable devices including inflatable tumor ablation, capacitive
volumetric strain sensor, and communication via inflatable radio frequency
antenna based on these structures are demonstrated.
