چکیده
ticle as: S.Y. Lee tions, Nano Energ Abstract A flexible GaN light-emitting diode (LED) has been fabricated on a liquid crystal polymer (LCP) substrate for biomedical applications. The bending radius and fatigue tests demonstrated the mechanically and optically stable characteristics of the GaN LEDs on the flexible substrates. A white light-emitting phosphor-coated GaN LED showed its potential as a next-generation flexible light source. A water-resistant and biocompatible polytetrafluoroethylene (PTFE) coated flexible LED detected prostate-specific antigen (PSA), which is expected to be used in future biomedical devices. & 2011 Elsevier Ltd.

متن کاملPolymer-based miniature flexible capacitive pressure sensor for intraocular pressure (IOP) monitoring inside a mouse eye.
This paper presents an ultra-thin and flexible polymer-based capacitive pressure sensor for intraocular pressure (IOP) monitoring in a mouse eye. Due to the size limitation of the anterior chamber in the mouse eye, a volume of approximately 700 × 700 × 150 μm(3) on a small substrate is available for the MEMS capacitive pressure sensor. Moreover, the sensor would ideally be easily injectable int...
