This paper reports a novel multi-functional self-powered pressure sensor with hierarchical wrinkle structure which is able to detect pressure as well as harvest the mechanical energy. Due to the utilization of hierarchical wrinkle structure, the device shows high sensitivity of 2.0 kPa-1 with the excellent response performance of 0.15 ms (rise-time) and 0.7 ms (release-time), respectively. In addition,...
This paper reports a single-step and cost-effective method to fabricate ultrathin Poly(dimethylsiloxane) (PDMS) membrane with honeycomb-like nanostructure on silicon substrate. The method is based on the template prepared by colloidal nanoparticles self-assembly. The thickness and nanostructure of the membrane are both determined by the size and surface morphology of two dimensional colloidal nanoparticles...
Percutaneous coronary intervention is the gold standard to coronary diseases in the past decades due to much less trauma and quick recovery. However, due to the traits of minimal invasiveness, clinicians have to defeat the difficulties in eye-hand coordination during the procedure, which also makes it a non-trivial task in the catheterization lab. The computer-aided surgical simulation is designed...
The computer-aided surgical simulation aims to provide an economic tool of effectiveness and convenience for the training process. In building this simulation system, the construction of the virtual anatomic environment is one of the major tasks. It provides the virtual tools with the scenario in which they are manipulated by the trainee. In intravascular surgery simulation, the surface model of the...
