Ingestible event markers with advanced circuitry and materials
The patent US12042302B2 describes an ingestible event marker designed to monitor and transmit signals within a biological environment. The marker consists of a multi-layered structure that includes a support, circuitry, and various conductive and anode materials. Specifically, the design features a signal amplifier encircling the circuitry, with multiple layers of anode and conductive materials strategically positioned to enhance signal transmission. Notably, the first layer of anode material is coupled to the circuitry, while the fourth layer of conductive material is placed opposite to it. The configuration aims to optimize the electrical properties of the marker, ensuring effective signal amplification through the use of materials such as magnesium for the anode and gold for the conductive layer.
Further claims detail specific characteristics of the marker, including the size of the anode material layers relative to the circuitry, the presence of air gaps to prevent direct contact, and the use of carbon ink as a conductive material. The design also emphasizes the importance of extending the anode and cathode layers beyond the circuitry's surface area to significantly increase the amplitude of the transmitted signals. For instance, the combination of the third layer of anode material and the fifth layer of cathode material extending beyond the circuitry is claimed to enhance signal amplitude by a factor of approximately 2.4. This innovative structure and material selection aim to improve the functionality of the ingestible event marker, potentially leading to advancements in medical monitoring and diagnostics.
