Smart Contact Lens for Intra-ocular Pressure Measurement |
| 초록 |
High intra-ocular pressure (IOP) can cause glaucoma and permanent vision loss. Therefore continuous measurement of IOP is an important factor for diagnosis of glaucoma. Here, we developed a resistive-based IOP sensor embedded smart contact lens for the measurement of IOP using the nanocomposite composed of silver nanowire (AgNW) with poly(dopamine) (PD) functionalized reduced graphene oxide (rGO) on polyethylene terephthalate (PET). The nanocomposite was directly patterned on PET and encapsulated by polydimethylsiloxane (PDMS) to resolve unnecessary loss of wires. PD enhanced the adhesive forces among AgNWs, rGO and polymer layers. The resistance of strain sensor increased from 0.01 to 1 MΩ as the IOP increased from 0 to 50 mmHg due to the disconnections among AgNWs. This IOP sensor was successfully integrated with application specific integrated circuit (ASIC) chips and micro-batteries for wireless glaucoma diagnosis and communication with external electronic devices. |
