This chapter introduces the concept of wireless interface, followed by the discussion of the fundamental items, concerning the fabrication of microsystems comprising low-power devices. Using as example, a design of a RF transceiver the frequency of 2.4 GHz and fabricated using a UMC RF CMOS 0.18 µm process, it will be discussed the main issues in the design of RF transceivers for integration in wireless microsystems. Then, it will be presented two biomedical applications for wireless microsystems: the first is a wireless EEG acquisition system, where it is presented the concept of EEG electrode and the characterisation of iridium oxide electrodes. The other application, is a wireless electronic shirt to monitoring the cardio-respiratory function. The main goal of these applications, is to improve the medical diagnostics and therapy by using devices which reduces healthcare costs and facilitates the diagnostic while at the same time preserving the mobility and lifestyle of patients.

In spite of the development of specific shielding of electronic devices as well as the current-day preference for bipolar sensing, electromagnetic interference (EMI) may still occur with certain pacemakers in certain settings, which in turn may lead to false inhibition of ventricular stimulation with potentially fatal consequences. The most important sources of clinically relevant EMI include medical diagnostics and therapy (e.g. magnetic resonance imaging, radiofrequency ablation, cardioversion/defibrillation, and electrocautery), the working environment (including high-power lines, combustion/degaussing/welding equipment, and others), as well as sources from daily life (such as wireless mobile phones, metal detectors, household appliances such as induction furnaces, electronic article surveillance devices, and others). To what extent, and whether or not at all, any given source of interference leads to EMI depends on several factors including the duration of interference, the field strength, and the frequency spectrum of the source. In addition, lead properties and device programming are important determinants. Awareness, recognition, and avoidance of EMI sources is of paramount importance, particularly in high-risk pacemaker-dependent individuals. The importance of proper education of patients as well as healthcare providers cannot be overemphasized.

And Chemical Properties

In vivo radionuclide generators make complex combinations of physical and chemical properties available for medical diagnostics and therapy. Perhaps the best-known in vivo generator is 212Pb/212Bi, which takes advantage of the extended half-life of 212Pb to execute a targeted delivery of the therapeutic short-lived α-emitter 212Bi. Often, as in the case of 81Rb/81Kr, chemical changes resulting from the transmutation of the parent are relied upon for diagnostic value. In other instances such as with extended alpha decay chains, chemical changes may lead to unwanted consequences. This article reviews some common and not-so-common in vivo generators with the purpose of understanding their value in medicine and medical research. This is currently relevant in light of a recent push for alpha emitters in targeted therapies, which often come with extended decay chains.
