Title: Chemical sensors based on chipless radio frequency identification (rfid) architectures
Inventor: GIBSON GEORGE A
IPC: G01N27/04
Filed: 2017-05-02
Abstract: A method and structure for a radio frequency identification (RFID) sensor that may be used to monitor various environmental conditions.

Inventor: BALIAN RAFFI
IPC: A61K8/02
Filed: 2016-06-15
Abstract: The present invention relates to a method for forming coated particles, comprising the steps of: agitating a volume of core particles while heating to a constant average temperature of about 40oC. Once particles are generally evenly mixed, with no apparent agglomeration, the vinyl-functional silicone polymer, hydride-functional crosslinker, and metal catalyst are combined in a premix under continuous propeller-mixing. The vinyl-functional silicone polymer, hydride-functional crosslinker, and metal catalyst premix is then siphoned into the main vessel, containing the heated core particles, at rate that ensures no clumping or agglomeration of the particulates. Once even coating has been achieved, the main vessel is heated to an average temperature of about 80oC, then cooled back down to room temperature (about 20oC-28oC). The coated material is then passed through a 45µm sieve to remove any large particulates that may be present.
