A 3D Sensor Fabricated by Layer-Based Additive Manufacturing and Printed Interconnect
Keywords: Layer-based Addititive Manufacturing, Printed Interconnect, 3D Sensors
Traditional electronics have generally been constrained to two dimensions. Fully three dimensional off-axis component placement and routing have only recently been explored with monolithic substrates. Solid freeform fabrication provides the means of creating a dielectric substrate of any arbitrary and complex shape suitable for these electronics including sockets for components. Direct Print dispensing of conductive inks or epoxies onto these substrates has been reported previously for electronics applications, but was generally confined to two dimensions in a fashion similar to traditional electronics. This paper describes a demonstration prototype of a 3D magnetometer sensor with micro-controller in a single 3D substrate.
