UHF RFID技术的提出，可以促进新的无源辅助技术。舌头控制人机界面首先讨论的标签是附着在口腔的硬腭和标签打开功率观察到响应舌头接近度而变化。其次，可拉伸标签由含有导电银纤维的莱卡织物制成。向弹性标签施加应变再次导致读取器处激活标签所需的功率成比例地变化。这种弹性标签被提议作为一种临时的皮肤安装应变计，可以检测身体上无行为能力的人的面部或颈部的肌肉抽搐。这两种设计都可以应用于电动轮椅的转向功能，或者便于控制计算机鼠标。在舌切换情况下实现了优于3dB的隔离，并且对于应变计观察到每百分比拉伸约0.25dBm。
UHF RFID technology is presented that can facilitate new passive assistive technologies. Tongue control for human computer interfaces is first discussed where a tag is attached to the hard palate of the mouth and the tag turn-on power is observed to vary in response to tongue proximity. Secondly, a stretchable tag is fabricated from Lycra fabric that contains conducting silver fibres. The application of strain to the elastic tag again causes the required power at the reader to activate the tag to vary in proportion. This elastic tag is proposed as a temporary skin mounted strain gauge that could detect muscle twitch in the face or neck of an otherwise physically incapacitated person. Either design might be applied to the steering function of a powered wheelchair, or to facilitate the control of a computer mouse. Better than 3dB isolation is achieved in the tongue switching case and approximately 0.25dBm per percentage stretch is observed for the strain gauge.
