An implantable polymer-based pressure sensor featuring an electrical LC-tank resonant circuit for passive wireless sensing without power consumption on the implanted site. The sensor is microfabricated with parylene to create a flexible coil substrate that can be folded for smaller physical form factor during implantation, and can be stretched back without damage for enhanced inductive sensor-reader coil coupling. Data received from the sensor can be enhanced to provide improved pressure measurements at increased distances.

An implantable glaucoma drainage device (GDD) system is disclosed. The GDD system comprises a microflow control system for controlling intraocular pressure, a protective capillary carrier tube housing the microflow control system, and anchoring arms holding the implanted device in place. The overall GDD size can be in a needle-implantable form factor for minimally invasive implantation. The GDD may be implanted via subconjunctival needle implantation to mimic the normal aqueous humor drainage pathway.

A method for fabricating a pair of large surface area planar electrodes. The method includes forming a first template above a first substrate, the first template having a first plurality of pores, coating the first plurality of pores of the first template with a first layer of conducting material to form a first electrode, placing the first plurality of pores of the first electrode in proximity to a second electrode, thereby forming a gap between the first plurality of pores and the second electrode, and filling the gap with an electrolyte material.
