Design and Fabrication of a Portable 1-DOF Robotic Device for Indentation Tests

There are many tactile devices for indentation examinations to measure mechanical properties of tissue. The purpose of this paper is to develop a portable indentation robotic device to show its usability for measuring the mechanical properties of a healthy abdominal tissue. These measurements will help to develop suitable mathematical models representing abdominal tissue. A 1-DOF portable robot...

A Novel Portable Scissors-Type Fruit Picking Device

At present, the fruit picking in most countries still largely relies on manual operation. Manual fruit picking can protect the fruits from damage during the operation process. However, it is time-consuming and labor-intensive, and poses a potential safety risk to the workers while working at heights not reachable. Therefore, a variety of fruit picking machines and platforms have been developed ...

Frames of Reference for Portable Device Interaction

Increasingly, our mobile devices are acquiring the ability to be aware of their surroundings, both their physical environments and their digital neighbourhoods. Alongside this awareness of the outside world, these devices are acquiring the ability to sense what is happening to them how they are being held and moved. The coincidence of connectedness, awareness and richly multimodal input and out...

Portable Device for High Resolution ECG Mapping

Portable device for multi-channel ECG measurement and body surface potential (BSP) mapping is introduced and its possible application for cardiac diagnostic is presented. The device is designed for simultaneous measurement of up to 144 body surface potentials relatively to a relocatable reference electrode. Use of active electrodes, driven grounding electrode and battery operation of the device...
