Corrosion Study of Implanted TiN Electrodes Using Excessive Electrical Stimulation in Minipigs [PDF]
Metals, 2019 (1) Background: Titanium nitride (TiN) electrodes have been used for implantable stimulation and sensing electrodes for decades. Nevertheless, there still is a discrepancy between the in vitro and in vivo determined safe charge injection limits.

Grip control and motor coordination with implanted and surface electrodes while grasping with an osseointegrated prosthetic hand [PDF]
Journal of NeuroEngineering and Rehabilitation, 2019 Background Replacement of a lost limb by an artificial substitute is not yet ideal. Resolution and coordination of motor control approximating that of a biological limb could dramatically improve the functionality of prosthetic devices, and thus reduce ...

Multilayer 3D electrodes for neural implants [PDF]
Journal of Neural Engineering, 2019 Abstract Objective . In many applications, multielectrode arrays employed as neural implants require a high density and a high number of electrodes to precisely record and stimulate the activity of the nervous system while preserving the overall size of the array. Approach

A challenging case of transvenous lead extraction
Türk Kardiyoloji Derneği Arşivi, 2015 A 72-year-old male patient with a 7-year history of cardioverter-defibrillator (ICD) implantation was admitted to our clinic with pocket infection. One year prior to this admission, he had undergone an unsuccessful extraction procedure at another clinic,

Chronic Implantation of Electrodes into the Olfactory Bulb [PDF]
Nature, 1963 A PRECISE method of chronic implantation of large electrodes into brain structures is to locate the generator of a signal and then to place the electrodes in a manner which will record the maximum electrical activity. Freeman1 has developed such a method for implanting into the prepyriform cortex utilizing the electrical field produced in this area by ...

Smart Electrode Array for Cochlear Implants
2023 IEEE 36th International Conference on Micro Electro Mechanical Systems (MEMS), 2023 Cochlear implants made of standard silicone electrode array (EA) are currently used to stimulate the auditory nerve of patients’ cochlea. The implants have a proximaldiameter of 0.5mm and 2~3cm long composed of 20 bulk platinum electrodes and connection wires (Ø 25µm).
