In the past few weeks the US Patent & Trademark Office has published a series of patent applications from Google that relate to varying aspects of their Google Glass spin-off project for smart contact lenses. On the surface, the new contact lenses product appears to be one that will work with Google Glass as an accessory more than it being about an independent product. That may change over time as new patents arise, but for now it's a Google Glass accessory. Our initial report titled "Google takes their Glass Vision to Smart Contact Lenses," laid the foundation of this project. Our second report published yesterday covered a new micro camera system for these new smart contact lenses. Today's report covers a total of seven new patent applications related to this project with links to five of Google's patents so that you could further explore this project in greater depth on your own. Google covers such matters as integrating silicon chips right into a contact lens, a method of testing tears for irritants, a method of measuring heat generated near the eye and so much more.
Assembling Thin Silicon Chips on a Contact Lens
Overview of Google's Invention: Google notes that their invention is generally about a method of assembling a contact lens having a thin silicon chip integrated into it. In one aspect, a method includes creating a plurality of lens contact pads on a lens substrate and creating a plurality of chip contact pads on a chip. The method further involves applying assembly bonding material to the each of the plurality of lens contact pads or chip contact pads, aligning the plurality of lens contact pads with the plurality of chip contact pads, bonding the chip to the lens substrate via the assembly bonding material using flip chip bonding, and forming a contact lens with the lens substrate.
Google filed patent applications 20140085599 and 20140084489 by the same titled back in Q3 2013. The US Patent and Trademark Office published on March 27, 2014. Considering that this is a patent application, the timing of such a product to market is unknown at this time.

About Today's Cover Graphic
Our cover graphic covers several patent elements. In patent FIG. 1A of patent application #20140085602 we're able to see an illustration of an exemplary non-limiting system that includes a contact lens employing a hydration component to generate information indicative of a hydration level of an eye on/in which the contact lens is worn. Patent FIGS. 2A and 2B of patent application #20140087452 illustrates exemplary examples of non-limiting embodiments of a contact lens that collects tear fluid.
