Abstract
En 中文
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 push-button, 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 push-button 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.
