“…Additionally, such an electrical stimulation of afferents can ignore the mechanical structure of the mechanoreceptor to a certain extent; thus, this method has the potential to render haptics, keeping the footprint small even as EMS. As a result of the experiment, we confirmed it is possible to present a force of about 300 gf ( 2.94 N) [12], and the effect was enhanced by multimodal stimulation with visual and cutaneous sensation [13]. Here, [gf] stands for the unit of gram force and 1.0 gf = 1.0 × 10 −3 kgf = 9.8 × 10 −3 N. However, it has not been investigated in detail whether this method also works in other upper limb joints.…”

“…We especially focused on Golgi tendon organs, which are related to muscle tension and force. We targeted their nerves called Ib fiber from electrodes on the skin surface as a method that does not require the generation of actual movement [12][13][14]. In the previous report, we stimulated the dorsal wrist's tendon connected to the muscle that extends the wrist.…”

Many wearable interfaces have been proposed to present force to the upper limb and elbow joint. One way to achieve a compact wearable haptic interface is to use electrical stimulation, and we have suggested that transcutaneous electrical stimulation above the wrist tendon can produce force a sensation in the direction of the muscle stretching; however, it has not been investigated in detail whether the force sensation presented by the electrical stimulation of the tendon occurs in the upper limb joints. In this study, to investigate whether the force sensation is generated when applying electrical stimulation of the skin at the tendon or at the muscle belly of the biceps brachii muscle, we quantitatively evaluated the direction and amount of the force sensation under the aforementioned conditions. The results showed that the electrical stimulation of the tendon produced significant force sensation in the direction of elbow extension. On the other hand, in some participants, the electrical stimulation of the muscle belly worked as a supporting force, resulting in the sensation of weakened force perception. In general, we concluded that the sensation produced by muscle stimulation was different from that produced by stimulation of the tendon.

“…Our previous literature demonstrated that a force sensation could be generated by electrical stimulation of the tendon via the skin surface (referred to here as tendon electrical stimulation or TES), which can be presented with a small setup. We also showed that magnitude of the sensation could be controlled by adjusting the current parameters [1] (Figure 1). Unlike the presentation of a force sensation via electrical…”

“…In our previous TES literature [1] , electrical stimulation was applied via electrodes placed mainly on the surface of the skin directly above the tendon at the back of the wrist. The electrical current was controlled while applying electrical stimulation.…”

“…TES expresses a static continuous force, performed continuously while the object is in contact with and pushing the right hand. The electrodes are positioned on the back of the wrist, as in the previous experiment [1] , and two electrodes are placed so as to straddle the wrist joint ( Figure 6). For the electrical stimulation, we used a biphasic rectangular pulse wave with a frequency of 100Hz, which is decided as a parameter that produce clear sensation in preliminary trials referring to the previous literature, and a pulse width of 200μs, which is definitely same to the parameter of the literature.…”

Background Our previous studies have shown that electrical stimulation from the skin surface to the tendon region (Tendon Electrical Stimulation: TES) can elicit a force sensation, and adjusting the current parameters can control the amount of the sensation. TES is thought to present a proprioceptive force sensation by stimulating receptors or sensory nerves responsible for recognizing the magnitude of the muscle contraction existing inside the tendon, so it can be a proprioceptive module of a small-size, low-cost force feedback device. But there is also suspect that TES presents only strong, noisy skin sensation. From previous study, it was found that TES has some limitation on varying sensations. Methods In this study, in addition to characterizing the proprioceptive sensation induced by TES, we constructed a multimodal presentation system reproducing a situation in which force is applied to the hand was offered, so as to investigate whether TES contributed to the reproduction of haptics cooperating with other modalities, rather than disturbing them. Specifically, we used vibration to present a cutaneous sensation and a visual head mounted display (HMD) system to present simultaneous images. Using this system, we also evaluated the efficacy of TES itself and that of the multimodal system involving TES. Results We found that TES, along with visual and vibration stimulation, contributed to the perception of a certain force. Conclusions Thus, TES appears to be an effective component of multimodal force sense presentation systems.
