Abstract :
A novel packaging method for an intraocular pressure (IOP) sensor is presented. The device, which will be implanted during cataract surgery, is 5.75 mm in radius and has to be folded to pass through an incision of 2–3 mm. A solder-filled microchannel approach is used for the antenna fabrication and packaging. A prototype of the device is tested at 1.5 GHz. A plot comparing the transmitted and received power is presented. It is shown that an ultra-low power radio frequency (RF) chip can be powered above its minimal requirement. Heat-assisted repair of fractured antennas is also studied in the presented fabrication method.
