“…In this paper, we describe the testing of a UHF RFID tag in the form of a tongue proximity sensor to facilitate tongue control of a wheelchair or computer mouse communicating with a future reading system. The sensing tag structure was introduced in [19] with an initial tongue controlled target response for a single user described in [20]. In this paper, for the first time, the operation of the tag is established with multiple user testing and data is provided to indicate the training times required and the resulting accuracy of the tongue position sensing is assessed.…”

“…3 indicates how the tongue‐tag interaction distance d affects the backscattered power which is received by the reader antenna. This is because the backscattered power is proportional to the product of the power available at the tag and the realised gain [20]. The propagation index n has a value found empirically to be about four and which arises from lossy tissue loading effects.…”

“…Tongue control systems are described in [15–19], but they rely on wired connections from the mouth, or intrusive tongue piercings. The initial design of a wireless passive mouth tag for tongue sensing with no need for piercings was introduced in [19, 20].…”

Tongue control with low profile, passive mouth tags is demonstrated as a human-device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed targets. The rate at which users are able to learn accurate targeting with high accuracy indicates that this is an intuitive device to operate. The significance of the work is that innovative very unobtrusive, wireless tags can be used to provide intuitive human-computer interfaces based on low cost and disposable mouth mounted technology. With the development of an appropriate reading system, control of assistive devices such as computer mice or wheelchairs could be possible for tetraplegics and others who retain fine motor control capability of their tongues. The tags contain no battery and are intended to fit directly on the hard palate, detecting tongue position in the mouth with no need for tongue piercings.

“…The antenna was fabricated by conductive silver ink which was profiled onto a Temporary Transfer Tattoo material by using a stencil. The same authors proposed similar tag layouts acting as a tonguetouch controlled switch [15] or as a passive strain sensor [16] for assistive devices helping patients with severe movement impairments. The reported read distances were in the range of 80-120 cm depending on the position of the tag over the body.…”

Originally introduced by the Material Science community, the Epidermal Electronics is now collecting interest also among Antenna engineers for the potentiality to achieve thin and flexible sensing transponders that are suitable to application over the epidermis. Unlike conventional wearable antennas, which are generally decoupled by the lossy human body by means of spacers or shielding sheets, epidermal tags need to be placed at a very close touch with the skin thus providing poor communication capabilities. This paper investigates, by means of a detailed numerical and experimental study, the performance of an epidermal dual-loop tag for UHF Radiofrequency Identification (RFID) depending on the specific placement over different parts of the human body and for a variety of volunteers. An on-body tuning mechanism is also introduced and demonstrated in real applications at the purpose to improve the tag response and hence to enable the use of a same tag layout for all the UHF RFID bands and for several placement loci.

“…Thanks to the versatility of passive RFID technology, new applications are continually emerging. In particular, the passive tags are promising candidates to provide cheap, unobtrusive and completely maintenance-free wireless platforms in bodycentric sensing systems [3]- [5], [20]- [22]. Overall, these developments are building upon and extending the great amount of research on wearable antennas conducted during the past decade [23]- [28].…”

We present the simulation-based design of UHF RFID tags based on electro-textile antennas and analyze the impact of recurrent washing on their performance through measurements. The antennas were fabricated from silver plated stretchable fabric made of nylon and elastic fibers. We coated half of the tested samples with acrylic spray to compare the influence of recurrent washing on the performance of the coated and uncoated tags. The fully functional tags including the microchip were washed ten times in a household washing machine using a typical 40°C program and detergent. The performance of the tags was measured after each wash. Prior washing, the peak read ranges of the tags were over 5.5 m. After ten washing cycles, the read ranges of coated and non-coated tags were 1.5 m and 2.8 m, respectively.
