This work demonstrates the feasibility of an all-in-one system for the detection, monitoring and treatment of pressure ulcers using two non-invasive methods, namely impedance spectroscopy and transdermal drug delivery by iontophoresis. The purpose of this device is to detect these chronic skin wounds at an early stage and treat them locally by delivering a vasodilator. The developed wearable flexible electrodes coupled to the compact electronic device used as a controlled current source show an increase in drug penetration by a factor of up to 8 for a current of 250 µA in comparison to passive diffusion.

Widely used in microelectronics and optoelectronics; Gallium Arsenide (GaAs) is a III-V crystal with several interesting properties for microsystem and biosensor applications. Among these; its piezoelectric properties and the ability to directly biofunctionalize the bare surface, offer an opportunity to combine a highly sensitive transducer with a specific bio-interface; which are the two essential parts of a biosensor. To optimize the biorecognition part; it is necessary to control protein coverage and the binding affinity of the protein layer on the GaAs surface.

The fifteen year long practice of loco-regional anaesthesia for cataract surgery has led, because its growing complexity (operating microscope, extra-capsular procedure, IOL) to improving neuroleptanalgesia. The actual step using a weak dose of Propofol is described. The akinesy of patient and eye permits that kind of surgery, well accepted without the risks of deep general anaesthesia with intubation.
