A new method to enhance the energy density of lithium (Li-ion) batteries has been developed by Yuan Yang, an assistant professor of materials science and engineering at Columbia Engineering.
Engineers at the University of Cambridge have developed a new, ultralow power transistor that operates by scavenging energy from their environment. This latest transistor could pave the way for new electronic applications such as implantable or wearable devices that can function continuously, for months or even years, without a battery by drawing energy from their environment. Devices based on this transistor can significantly reduce the amount of power used.
Electronics that can be embedded in clothing are a growing trend. However, power sources remain a problem. In the journal Angewandte Chemie, scientists have now introduced thin, flexible, lithium ion batteries with self-healing properties that can be safely worn on the body. Even after completely breaking apart, the battery can grow back together without significant impact on its electrochemical properties.
A new generation of electronics has been inspired by LEDs, however more research is still required to make luminescent materials that have prolonged lifespan and consume less energy. Although a few inorganic metals appear promising, they are rare, expensive to process, and likely to be toxic.
Technological development in the near future will see more transistors being placed into much smaller areas within computer chips. MIT engineers state cell phones, laptops, and other electronic gadgets are likely to face a greater risk of overheating, resulting in interactions between electrons and heat-carrying particles known as phonons.
In response to an external electric field, 'ferroelectric' materials tend to switch between different states of electrical polarization. This flexibility indicates that they hold promise for several applications. including computer memory and electronic devices.
Batteries used in smart phones as well as other portable electronic devices normally dry out during inopportune times. Scientists have attempted to create fibers as an alternative to batteries and incorporate these fibers in clothing to power these portable devices.
