Electronics systems designed with a smart approach can effectively improve our life by means of some features that can be included in the objects that we use every day inside our houses, offices, studies, cars and so on.
Moreover, smart electronics objects can be integrated and communicate with each other in an automatic mode, giving us the chance to enjoy the advantages of a comfortable life.
In the previous parts of this blog series I described the first points of the list below:
- SMART SENSING (Smart Life: The Intelligence of Electronics Improving Our Lives, Part 1)
- SMART LIGHTING (Smart Life: The Intelligence of Electronics Improving Our Lives, Part 2)
- SMART MOTOR CONTROL (Smart Life: The Intelligence of Electronics Improving Our lives, Part 3)
- SMART BRAIN (Smart Life: The Intelligence of Electronics Improving Our Lives, Part 4, Smart Life: The intelligence of Electronics Improving Our Lives, Part 5)
- SMART POWER
Let’s deal now some examples of new electronic products that have been presented by the STMicroelectronics Company at the i-Sedex 2014 edition in Seoul, Korea, that belong to the smart power sector.
Smart power technology is based on the wireless charging of electronics devices. The application circuit has a rechargeable battery that is charged by mean of a wireless setup which transmits the electromagnetic energy from a transmitter coil to a receiver coil (see Figure 1):
Wireless charging, also known as inductive charging is based on a few simple principles. The technology requires two coils: a transmitter and a receiver. An alternating current is passed through the transmitter coil, generating a magnetic field. This in turn induces a voltage in the receiver coil; this can be used to power a mobile device or charge a battery. (Source: Wireless Power Consortium WPC)
The system is powered by mean of a microcontroller that is the computing core of the system and controls a set of sensors and actuators to realize multiple functions:
Demonstrated at i-SEDEX, ST’s wireless charging solution for multiple platforms supports different standards and sub-standards, developed by Wireless Power Consortium (WPC) and Power Matters Alliance (PMA). (Source: STMicroelectronics web press releases)
The smart power technology is a good solution for all the applications that require a wireless charging of the batteries and it is recommendable for a very interesting project that has been presented at the Saie Smart City Exhibition 2014: the mHealth project (see Figure 2)
The MHealth is a system that is wearable and it is intended to lead a patient with Parkinson syndrome to move inside a smart home by mean of audio and vibrational simulation. It acts as an e-doctor that evaluates and drives the movements of a patient in a real time mode and it might improve his life, especially in case of atypical syndromes, that are very difficult to treat. The batteries of this smart wearable electronic system might be recharged in a wireless mode to feed the system in a semiautomatic mode and to guarantee a longer timeframe between a maintenance checkup of the system and the next one. A smart home is the perfect environment for a remote assistance of a patient.
What do you think of smart power? Do you think that wearable systems like mHeath might improve effectively the quality of the life of persons who, unfortunately, are affected by Parkinson syndrome?
