Field effect devices, such as capacitors and field effect transistors, are used to interact with neurons. Cubic silicon carbide is biocompatible with the neuronal environment and has the chemical and physical resilience required to withstand the body environment and does not produce toxic byproducts. It is used as a basis for generating a biocompatible semiconductor field effect device that interacts with the brain for long periods of time. The device signals capacitively and receives signals using field effect transistors. These signals can be used to drive very complicated systems such as multiple degree of freedom limb prosthetics, sensory replacements, and may additionally assist in therapies for diseases like Parkinson's disease.

A system for providing a standard electrocardiogram (ECG) signal for a human body using contactless ECG sensors for outputting to exiting medical equipment or for storage or viewing on a remote device. The system comprises a digital processing module (DPM) adapted to connect to an array of contactless ECG sensors provided in a fabric or the like. A selection mechanism is embedded into the DPM which allows the DPM to identify body parts using the ECG signals of the different ECG sensors and select for each body part the best sensor lead. The DPM may then produce the standard ECG signal using the selected ECG signals for the different body parts detected. The system is adapted to continuously re-examine the selection to ensure that the best leads are selected for a given body part following a movement of the body part, thereby, allowing for continuous and un-interrupted ECG monitoring of the patient.
