Tactation is the sensation perceived by the sense of touch, and is based on the skin’s receptors. Touch is a common medium used by the general population and the sensory impaired. Tactile substitution can be used by the blind or deaf in order to: (a) enhance access to computer graphical user interfaces and (b) enhance mobility in controlled environments.The skin nerves can be stimulated through six...
This paper discusses state-of-the-art tactile displays fabricated by a micro-electronic-mechanical-system (MEMS). A tactile display conveys tactile sensations to users by using actuators. Traditional tactile displays consist of large size actuators, such as a motor or an ultrasound vibrator, to convey tactile feedback by vibration. In addition, the tactile sensation of traditional displays has poor...
MEMS (microelectromechanical systems) are used in many fields including display applications, which are extensively studied both in academia and industry. For practical devices, numbers of advanced technologies have been developed based on MEMS concept. For display technologies, projection displays, reflective displays, transmissive displays and other display modes have been achieved by different...
Reliability of MEMS (MicroElectroMechanical-Systems) devices is a crucial aspect as it can discriminate the successful from partially or totally missed reaching of Microsystem technology based market products. However, the topic of MEMS reliability is significantly articulated, as it comprises numerous physics of failure and diverse failure mechanisms. Thereafter, it requires a pronounced sensitivity...
