Tactile display has recently been attracting much attention in the field of human computer interaction. There is a strong need for such a device especially for surgeons who need to feel the tissue hardness during laparoscopic surgeries. The concept of design is built upon simple use of several springs which are made from Shape Memory Alloy, SMA, to control(More)
This paper describes a novel mobility assistive device under development in the Egypt-Japan University of Science and Technology (E-JUST). The proposed system can help patients who do not have enough physical strength on the lower limbs during sit to stand due to aging, diseases such as polymyositis and myopathy, and joint replacement surgery complications.(More)
Many places in the world are heavily contaminated with landmines, which cause that many resources are not utilized. This makes landmine detection and removal challenges for research. To guarantee reliable landmine sensing system, deep analysis and many test cases are required. The proposed concept is based on application of 1 kPa external constant pressure(More)
A macroscale tactile sensor using a resistance-type strain gauge is presented to demonstrate the concept of applying two sensors with considerably different stiffnesses to soft tissue for compliance detection. The design procedure for the tactile sensor was carried out. The sensor contains two cantilevers with different stiffnesses. One important advantage(More)
Unexploded Landmines, after wares, represent a serious problem, wastes life and money. Recent research states that contact sensors are promising. In this work, a novel contact sensor for landmine detection is presented. The sensor principle is based on the concept of 2-DOF vibration absorber system (two springs and two masses), to detect the presence of an(More)
Tactile display is recently attracting much attention in the field of human computer interaction. There is a strong need for such a device especially for application in which the touch feeling is lost, such as surgeons willing to feel the tissue hardness during laparoscopic surgeries. In this paper, a novel multi-modal tactile display device which can(More)
