In this paper, a novel 3D and inkjet printed pressure-sensing button-shaped resonator is proposed. The button is fabricated using fast, cost-effective, flexible and environment friendly stereolithography (SLA) 3D printing and inkjet printing techniques. The resonant frequency of the button can be tuned from 2.7 GHz, for idle status, to 1.6 GHz, for a hard press. This design can be used for applications such as gesture detection for Internet of Things (IoT) devices and wireless pressure monitoring for buildings and constructions.
