Bionic ear prosthesis: the coming future

Design and Testing of a Bionic Dancing Prosthesis

Traditionally, prosthetic leg research has focused on improving mobility for activities of daily living. Artistic expression such as dance, however, is not a common research topic and consequently prosthetic technology for dance has been severely limited for the disabled. This work focuses on investigating the ankle joint kinetics and kinematics during a Latin-American dance to provide unique m...

Bionic Leg Prosthesis Emulates Biological Ankle Joint during Walking

Figure 1. The bionic prosthesis’ mass of 2.0 kg is equivalent to a biological foot and partial shank of an 80 kg person. The prosthesis includes a carbonfiber in-series leaf spring, unidirectional parallel leaf spring, and heel and forefoot leaf springs that provide elasticity. A series-elastic actuator performs negative and positive work. The actuator is comprised of a 200-Watt DC brushless mo...

Micromechanical resonator array for an implantable bionic ear.

In this paper we report on a multi-resonant transducer that may be used to replace a traditional speech processor in cochlear implant applications. The transducer, made from an array of micro-machined polymer resonators, is capable of passively splitting sound into its frequency sub-bands without the need for analog-to-digital conversion and subsequent digital processing. Since all bands are me...

The Past, Present and Future of Bionic Vision

The WHO, world health organization, estimated that in 2002 there were 161 million (about 2.6% of the world population) visually impaired people in the world. This staggering number leads many researchers and scientist to develop methods and devices to aid or cure blindness. This paper goes over the current and past methods used to help the blind as well as future research into methods that wil...
