Tuning Infill Characteristics to Fabricate Customizable 3D Printed Pressure Sensors

Published: 01 May 2024 Publication History

Abstract

We present a novel method for fabricating customizable pressure sensors by tuning the infill characteristics of flexible 3D prints, addressing the demand for precise sensing solutions across a range of applications that require variable softness. While infills are conventionally viewed as supportive structures in 3D printing, our work shifts the focus toward their potential to create compressive structures. Our demonstration highlights how different infill patterns and densities influence the mechanical behavior of 3D printed objects. Consequently, we demonstrate the versatility of this method through the fabrication of sensors for three exemplary applications, each with varying sensing needs.
