제목 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 transparent IOP sensor embedded smart contact lens for the measurement of IOP using the fragmentized silver nanowire (f-AgNW) with sandwich-structured parylene C. The f-AgNWs were directly patterned on the parylene C substrate and encapsulated by another parylene C layer to resolve unnecessary loss of wires. The experiments of IOP monitoring with transparent smart contact lens were carried out on the bovine eye. The IOP monitoring smart contact lens shows about 3% of resistance changes as increasing IOP level from 0 to 50 mmHg. 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.
