Additional use cases for RFID tags by implementing 3D printed push-button functionalities

Abstract

Passive ultra-high frequency (UHF) radio frequency identification (RFID) tags can be embedded to objects and to the surrounding environment for identification and sensing. The potential of the technology can be further increased by designing new features, such as push-button functionalities, to the tags. In this study, the additional features were created in a unique way through 3D printing, as it enables the designing and manufacturing of versatile and individually tailored products. The first prototype was created around a commercial tactile pushbutton, while the second prototype was fully self-designed and based on thick two-sided tape and copper tape. These kinds of structures can be used to sense the state of the battery-free pushbutton wirelessly from a distance. Both prototype devices were found to be fully functional when tested with a hand-held RFID reader from a 1-meter distance by 4 people. Finally, care professionals were gathered to ideate versatile future use cases for the developed push-button prototypes as an assistive technology. New possibilities for using the buttons were identified especially for persons with limited cognitive and physical capabilities. The next steps are to first design special-purpose push-button objects based on these ideas and then 3D print prototypes of these objects.

WearNControl: Textile-Based Multimodal Customizable Activators

“…Recently, work has been done to implement activators, such as buttons, into clothing and into surroundings for wearable wellbeing, home-automation, and assistive solutions. A few examples include passive ultra-high frequency (UHF) radio frequency identi cation (RFID) tags combined with 3D-printed pushbuttons, which are battery-free, lightweight, and easy to integrate into surroundings [15], Internet of Things (IoT)-based wearable devices and arti cial intelligence (AI)-based tools for human-computer interaction in assisted living, and a control system to provide a platform using the power of AI to interact with diverse technologies for improving user's daily life [16]. Further, [17] has proposed a home panic button that uses a NodeMCU ESP8266 microcontroller to send a message via Message queuing telemetry transport (MQTT) to a web subscriber, notifying them of the emergency and providing a map of the area to ensure a secure, exible, and reliable system for public security.…”
