TECHNOLOGY OVERVIEW

Wearable electronics is a US$116.2B dollar market that is only expected to grow exponentially with the increasing demand and use for wearable technologies in sectors such as healthcare and smart devices. One of the main limiting factors of this technology is the battery life which can be broken down to either having clunky charging capabilities or poor lasting time. Therefore, there is a need for either a better charging method or better performance for the battery.
 

This technology offer is a flexible and stretchable printed battery that provides seamless charging method via sweat. This battery is small (2x2cm) and can be charged with only 2mL of sweat to provide 20hrs worth of power. The battery can be used as either the primary or secondary source of power and can be printed on a variety of materials such as textiles. It contains no heavy metals or toxic chemicals which eliminates the problem of harmful electronic waste. The battery is also highly durable and can withstand strain from daily activities. Also, the slim nature of battery makes it less intrusive and allows for wider design options for wearable electronics.

TECHNOLOGY FEATURES & SPECIFICATIONS

This technology is a flexible and stretchable printed battery that can be charged by sweat. Features of this technology are as follows;

  • Printed battery with ink (silver flakes and hydrophilic poly(urethane-acrylate))
  • Printable on different materials (eg. Textiles)
  • Small (2x2cm)
  • Flexible and stretchable
  • Non-intrusive charging (Sweat as source)
  • Output power sufficient to power commercial sensors etc.
  • No heavy metals or toxic chemicals

POTENTIAL APPLICATIONS

The uses of this technology are for industries that are interested in wearable electronics or battery manufacturers. Potentials applications include but are not limited to:

  • Healthcare (monitors, sensors)
  • Sports (GPS trackers, fitness monitor)
  • Smart Devices (smartwatch, smartglasses)

The technology owner is looking to out-license this technology to developers or manufacturers in the wearable electronics or battery industry.

Market Trends & Opportunities

The wearable electronics market is expected to growth at a CAGR of 18% to be worth US$265.4B by 2026. This technology can address the intrusive charging issue of the wearable electronics market.

Benefits

  • Seamless charging (on-the-go charging via sweat)
  • Adaptable (sweat-powered battery can act as primary or secondary source of power)
  • Small (allows for greater design choice)
  • Durable
  • Environmentally friendly
