By utilizing the progress of electronics technology, we might deeply enhance the potential benefits of a type of interactive and smart approach, especially in the case of large companies in the field of microelectronics investing in the creation a portfolio of wearable/implantable devices for medical applications, such as STMicroelectronics Company does (see Figure 1):
“STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has introduced the MIS2DH, an ultra-low-power 3-axis accelerometer specifically designed for medical applications, including implantable devices classified by U.S. Food and Drug Administration (FDA) as Class III. ST has many years of experience in developing custom motion sensors for leading medical-equipment manufacturers and the MIS2DH distils this expertise into an off-the-shelf solution that can enable functions such as activity monitoring and posture sensing to be included in a wide range of medical applications. Implantable medical devices such as cardiac pacemakers, ICDs (Implantable Cardioverter Defibrillator), and neurostimulators have been successfully used for many years to prolong the lives of patients with heart problems or to make life better for people with chronic pain conditions. Today, there is a growing interest in the medical world in exploring how new implantable devices could help treat other chronic problems such as high blood pressure, epilepsy, and tremor-related conditions. For most of these applications, an embedded accelerometer capable of measuring the activity and posture of the patient is important to manage the stimulus delivered by the implantable device and therefore to improve the effectiveness of the treatment and the wellbeing of the patient.” (Source: www.st.com
The electronics solutions for e-health represent an increasing part of the Healthcare portfolio of many large companies in the electronics field; this demonstrates the importance of developing reliable, effective and safe devices: the design and engineering process of such devices is then a key step of this process (see Figure 2).
