Abstract

The rapid development of wearable electronics in recent years has brought increasing energy consumption, making it an urgent need to focus on personal energy harvesting, storage and management. Herein, a textile-based personal energy management device with multilayer-coating structure was fabricated by encapsulating commercial nylon cloth coated with silver nanowires into polydimethylsiloxane using continuous and facile dip-coating method. This multilayer-coating structure can not only harvest mechanical energy from human body motion to power wearable electronics but also save energy by keeping people warm without losing heat to surroundings and wasting energy to heat empty space and inanimate objects. Fluoroalkylsilanes (FAS) were grafted onto the surface of the film through one single dip-coating process to improve its energy harvesting performance, which has hardly adverse effect to heat insulation and Joule heating property. In the presence of FAS modification, the prepared film harvested mechanical energy to reach a maximum output power density of 2.8 W/m(2), charged commercial capacitors and lighted LEDs, showing its potential in powering wearable electronics. Furthermore, the film provided 8% more thermal insulation than...Continue Reading

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
