Wireless Brain Implant Using a Telemetric Electrode Array System
Posted in Bio-Medical, Electronics & Computers, Electronics, Implants & Prosthetics, Medical, Briefs, TSP, MDB on Tuesday, 01 September 2009

A 3D intra-cortical electrode array is embedded for signal acquisition, processing, and wireless communication.

The ability to monitor the activities of ensembles of single neurons is critically important in understanding the principles of information processing in the brain that underlie perception, cognition, and action. Multiple microelectrode recording using appropriate neuronal implants provides this ability. The Telemetric Electrode Array System (TEAS) project aims at developing and embedding a three-dimensional intra-cortical electrode array with all electronics required for signal acquisition, processing, and wireless communication entirely into the head.

Microfluidic Extraction of Biomarkers Using Water as Solvent
Posted in Bio-Medical, Electronics & Computers, Electronics, Medical, Patient Monitoring, Briefs, MDB on Friday, 01 May 2009

Terahertz modulation of permittivity of water would enable solvation of molecules of interest.

A proposed device, denoted a miniature microfluidic biomarker extractor (μ-EX), would extract trace amounts of chemicals of interest from samples, such as soils and rocks. Traditionally, such extractions are performed on a large scale with hazardous organic solvents; each solvent capable of dissolving only those molecules lying within narrow ranges of specific chemical and physical characteristics that notably include volatility, electric charge, and polarity. In contrast, in the μ-EX, extractions could be performed by use of small amounts (typically between 0.1 and 100 μL) of water as a universal solvent.
