“…There have been a large number of reports on the conventional rigid stimulators to provide feedback to humans. [19][20][21][22][23][24][25][26][27] These devices were usually integrated into gloves [20][21][22]27] and clothes [23,25] to achieve wearability, and interested readers are referred to a comprehensive review on those devices by Yin et al [28] However, wearing comfort of such devices is rather limited. First of all, the weight of the rigid stimulator may exceed that of ordinary clothes, which created physical burden to the wearer.…”

On‐skin electronics have been widely used in fields, such as wearable healthcare and human–machine interfaces due to their excellent performances and wearable comfort. Among them, on‐skin sensors for collecting signals have been greatly developed, while the stimulators that provide tactile feedback are difficult to achieve in terms of flexibility and stretchability due to their rather complicated structures. Achieving on‐skin stimulators with superior performances and outstanding wearability requires major advances in materials, fabrication, and structure design. The on‐skin stimulator needs to be soft with a lightweight and thin structure so that it can be laminated onto the skin with conformal contact for accurate feedback. Three stimulation modes, namely electrotactile, thermal, mechanotactile, and vibrotactile stimulation, are investigated. Among them, electrotactile stimulation is the characteristics of high resolution and quick response. Thermal stimulation can provide a unique heat sensation without crosstalk with other stimuli. Mechanotactile and vibrotactile stimulation can bring comfortable feedback to skin, showing great potential in wearable applications. This paper summarizes the working principles, materials, structures, and applications of these on‐skin stimulators, and compares their advantages with conventional rigid devices. At the end of this paper, the challenging issues and future prospects in this field are discussed.

“…Vibrotactile stimulation is capable to provide amputees with the extraordinary sensing of embodiment in their prosthetic when installing at the forearm of the patients [48]. On the other hand, five spot vibration feedback actuators are distributed over the fingers of healthy hand, with one motor for each finger, in order to detect the level of the contact pressure that was created by a virtual sensory system [49]. The C2 tactors are very effective to convey the tactile information to the subjects' brain when using as a haptic wearable belt fixed around the amputees' waist [50].…”

A sense of touch is essential for amputees to reintegrate into their social and work life. The design of the next generation of the prostheses will have the ability to effectively convey the tactile information between the amputee and the artificial limbs. This work reviews non-invasive haptic feedback stimulation techniques to convey the tactile information from the prosthetic hand to the amputee's brain. Various types of actuators that been used to stimulate the patient's residual limb for different types of artificial prostheses in previous studies have been reviewed in terms of functionality, effectiveness, wearability and comfort. The non-invasive hybrid feedback stimulation system was found to be better in terms of the stimulus identification rate of the haptic prostheses' users. It can be conclude that integrating hybrid haptic feedback stimulation system with the upper limb prostheses leads to improving its acceptance among users.

“…The current methods that deliver tactile stimulation are limited, and most adopt the vibro-tactile techniques [10][11][12]. While they have proven to be quite successful in sending a stimulus to the mechanoreceptors, they are limited in stimulus variation and provide a stimulus that is not very common in real-world interactions, as they send signals through controlled frequencies [13].…”

“…Systems by Li et al [10], Markovic et al [11], and Marasco et al [12] all utilize the vibro-tactile approach to deliver a sensation that is used in aiding the user in completing a task of dexterity. Their effectiveness has varied, and there is much room for improvement and more diverse methods of tactile stimulation that can support new ways of generating sensations.…”

Experimental Analysis of a Novel, Magnetic-Driven Tactile Feedback Device

The study presented in this paper details the development and experimental testing of a novel, magnetic, tactile feedback device that is able to deliver a stimulus to a patch of skin on the lower arm of a user. The device utilizes magnets to deliver a sensation that is not dependent on controlling specific frequency bands to stimulate the mechanoreceptors, as is the case with vibro-tactile methods. The device was tested on human volunteers to evaluate its ability to induce a response from the user through the magnetic interface. The study aims to quantify the ability of the user to sense the stimulus by analysis of the receiver operating characteristic (ROC) and delay in response under different experimental conditions. Three different speeds and two different distances were explored for the magnetic interface. A two-way, repeated-measures ANOVA with post-hoc analysis was performed for the percentage of correct responses, delay in response time, and area under the curve (AUC) of the obtained ROCs. The results showed that the different conditions had a significant effect on the number of correct responses and the AUC, but not on the delay. The magnetic interface thus needs to be optimized across different parameters to deliver the best detectable stimulus to the user. Future work includes further development of the device and working towards a comparative trial with other tactile feedback approaches.
