Internet of Things important power transmission and storage technology
Power transmission and storage technologies that may play an important role in the IoT path include:
1. Novel Battery Appearances: Like thin-film printed and flexible batteries that can be embedded in clothing or Thinergy, LG and others recently demonstrated products with thin, flexible cable batteries. Small battery size is also important for millimeter-scale system operation.
2. High-density batteries: Technologies such as siliconanodes that improve lithium battery performance are expected to improve battery performance and become smaller and lighter.
3. Power Harvesting: Some systems "harvest" from the environment to charge smart objects. Examples include electricity generated by mechanical motion such as vibration, heat sources, solar cells, electrostatic charges or electromagnetic radiation in the environment. Although mining usually generates only a small amount of electricity, it is sufficient for simple sensing and communication purposes. MicroStrain, for example, is introducing a straingaugesensor node that uses power harvesting technology.
4. Wireless Charging: Not all objects with sensing and communication functions can supply the required power with a replaceable battery or power supply. For example, smartclothing is troublesome when it comes to replacing a battery. In addition, promising IoT applications such as medical sensors implanted under the skin can not replace batteries. Under the auspices of the WirelessPowerConsortium and its rival organization A4WP, several systems are in initial mass production, while others are still in the research and development phase.
In addition, there is another kind of power technology has not yet fully developed potential for Internet of Things applications, that is, supercapcapacity, that is, supercapacitors capacitance. Although it is generally believed that it will become a battery replacement, existing products have the problem of excessive leakage. However, emerging trend groups should still be aware of whether the viability of future ultracapacitors will improve.
