Thick film force and slip sensors for a prosthetic hand
نویسنده
چکیده
In an attempt to improve the functionality of a prosthetic hand device, a new fingertip has been developed that incorporates sensors to measure temperature and grip force, and to detect the onset of object slip from the hand. The sensors have been implemented using thick film printing technology and exploit the piezoresistive characteristics of commercially available screen printing resistive pastes and the piezoelectric properties of proprietary lead-zirconate-titanate (PZT) formulated pastes. This paper describes the design and production of these different types of sensor and presents some results from initial investigations.

Development of a Tactile and Slip Sensor Controlled Prosthetic Hand System
Supported by the latest sensor and microcontroller technologies, prosthetic hands have been widely used to reclaim the human functionaries. Among these, the most advanced prosthetic hand was controlled by the tactile and EMG singles. However, for a slippery object, attention has to be taken for the inexperienced users who need to control the shrinkage of the wrist flexor carefully. In this pape...

Some of the traditional methods used to control a conventional prosthetic device are described alongside the current state of new control techniques and how they may progress. The review includes implantable myoelectric sensors and describes the potential of connecting directly to the peripheral nervous system. Control methods are then deduced for each technique, where the application is a six ...

Along with high sensitivity in detecting gas, the response and recovery times of semiconductor gas sensors are of considerable importance for real life applications. In most cases, the recovery time is more than the response time. At the same time, water vapor present in the ambient, is chemisorbed on the tin oxide, SnO2 surface and the water molecules dissociate into hydroxyl species, which ac...
متن کاملDesign and implementation of a voice-controlled prosthetic hand
Current hand prostheses are mostly driven by electromyography (EMG) signal, and existing experiments have proved that multichannel EMG signal controls are not suitable due to early fatigue problems and high effort requirements to perform even simple activities. Therefore, in this study we present a new voicecontrolled active hand prosthesis to perform several basic tasks. We first designed a no...
متن کاملEffect of Bubble/Droplet Morphology and Slippage on Attachment Induction Time in Deoiling Flotation Process
A modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. The role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. In this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...
