“…Despite that thermal perception differs across individuals, our findings showed that all participants were able to feel the different thermal intensities for both cold and warm stimuli when felt on the skin. As in prior work [52,28], our results overall also support the consistent finding that perception of cold thermal stimuli (whether participant sensitivity or detection times) is greater than warm stimuli. However, while higher thermal intensity made a few participants remark on the intense feeling, the comfort ratings indicate overall that this comfort is not different across contact medium.…”

“…With the rise of smartwatches, perhaps the most obvious area for thermal feedback is the wrist. Although researchers have explored the utility of thermal bracelets [52] for providing spatio temporal feedback, it has not been studied from the perspective of conveying emotional prosody. Given the physiological aspects of emotional perception, an alternative garment based solution might be more applicable.…”

“…As in prior work [20,52], we used Peltier elements (TEC1-12706 2 thermoelectric modules) as primary thermal actuators, given their capability of providing fast changes in temperature for creating cool or warm stimuli. For our first prototype to be used in Experiment 1, modules were controlled using a Proportional, Integral, Derivative (PID) controller to ensure accurate temperature control.…”

“…Our work shows that it is feasible to design wearable thermal voice augmentation displays (RQ1), which crosses multiple application scenarios such as augmenting personal experience [73], emotion model mapping [74], using thermal feedback as a notification mechanism [72,52], or augmenting voice message perception of intelligent voice assistants [31]. Our work adds to these findings, by showing that neutral spoken messages can be thermally augmented with the end goal of tuning the perceived valence and arousal of such voice messages, when emotional prosody may be situationally impaired (RQ2).…”

Voice is a rich modality for conveying emotions, however emotional prosody production can be situationally or medically impaired. Since thermal displays have been shown to evoke emotions, we explore how thermal stimulation can augment perception of neutrally-spoken voice messages with affect. We designed ThermalWear, a wearable on-chest thermal display, then tested in a controlled study (N=12) the effects of fabric, thermal intensity, and direction of change. Thereafter, we synthesized 12 neutrally-spoken voice messages, validated (N=7) them, then tested (N=12) if thermal stimuli can augment their perception with affect. We found warm and cool stimuli (a) can be perceived on the chest, and quickly without fabric (4.7-5s) (b) do not incur discomfort (c) generally increase arousal of voice messages and (d) increase / decrease message valence, respectively. We discuss how thermal displays can augment voice perception, which can enhance voice assistants and support individuals with emotional prosody impairments.

Conformable electronics has emerged in recent years as an innovative research field and the ability of conformable devices to monitor human physiological signals has been extensively explored. Therefore, in this study, the possibility of using conformable electronics as active devices capable of providing stimuli to the human body is investigated. In particular, a new approach is proposed to elicit tactile sensations on human skin using an operating principle based on the generation of localized heat in correspondence with a closed volume of air. This latter consequently expands causing the deformation of a thin membrane. The use of fast prototyping fabrication techniques, i.e., inkjet printing, and commercially available materials, i.e., transfer tattoo paper, allow the device to be produced quickly and easily transferred on the target substrate. Despite the ultrathin thickness (few micrometers), it is possible to observe forces and displacements thanks to localized heating at very low working powers (<300 mW). A pilot test on a voluntary subject demonstrates how it is possible to discriminate the tactile sensation elicited by the active tattoo device. While the working principle on a single taxel is demonstrated, these results show the potential of the new approach for developing wearable tactile displays.
