“…The stimuli on the order of 10-100 mN and 10-100 µm are the typical perception thresholds in a static position; but if hand movement (dynamic condition) is permitted, 0.85 µm in the height of surface vertically could also be perceived [17][18][19][20]. When considering the friction perception in the horizontal direction, humans can detect the changes in tangential force and displacement at around 40-50 mN [21] and 0.2 µm [22,23] in the ultrasonic vibration range, such as in 20 kHz-40 kHz [24]. Further increased ultrasonic frequency may lead to degradation in spatial resolution and attenuation of sound pressure in the air.…”

Haptic technology that provides tactile sensation feedback by utilizing actuators to achieve the purpose of human–computer interaction is obtaining increasing applications in electronic devices. This review covers four kinds of electromechanical actuators useful for achieving haptic feedback: electromagnetic, electrostatic, piezoelectric, and electrostrictive actuators. The driving principles, working conditions, applicable scopes, and characteristics of the different actuators are fully compared. The designs and values of piezoelectric actuators to achieve sophisticated and high-definition haptic effect sensations are particularly highlighted. The current status and directions for future development of the different types of haptic actuators are discussed.

“…The predominance of PCs in vibrotactile perception meant early systems typically used amplitude modulation around 200-250 Hz, close to peak sensitivity of these mechanoreceptors (e.g., systems by Iwamoto [6], Carter [7], Palovuori [80], Korres [81]). However, there is also evidence that amplitude modulation can stimulate Meissner corpuscles (MCs), which are sensitive to lower frequency vibrations [57].…”

Ultrasound haptics is a contactless haptic technology that enables novel mid-air interactions with rich multisensory feedback. This paper surveys recent advances in ultrasound haptic technology. We discuss the fundamentals of this haptic technology, how a variety of perceptible sensations are rendered, and how it is currently being used to enable novel interaction techniques. We summarize its strengths, weaknesses, and potential applications across various domains. We conclude with our perspective on key directions for this promising haptic technology.
