The Internet of Disposable Things (IoDT) With A Biobattery
Mostly every home has now this kind of utilities — wireless speakers, printers, smart watches, smart boards, pet feeders and many more.
Of the most valuable thing about Internet of Things is that they have wireless sensors which are connected to the internet and can provide up to date information. For instance, a sensor could be included in any food item (to its’ package) and can monitor different predefined conditions: freshness, quantity left inside and so on.

Seokheun Choi, associate professor of electrical and computer engineering at Binghamton University said that availability of sensors and internet constructed a new paradigm — Internet of Disposable Things (IoDT):
“This novel technique, constructed in a small, compact, disposable package at a low price point, can connect things inexpensively to function for only a programmed period and then be readily thrown away.”
Battery is the only one issue, because these sensors must be very small, light and last for a big period of time. Seokheun Choi is working on constructing a long lasting solution for this kind of demand. His team once created a small – size microbial fuel cells. They had issues with low power density and energy-intensive fluidic feeding operation.
Researchers at Binghamton University, State University of New York have developed a micro biobattery that could power these disposable sensors.
A small-power, disposable, solid-state battery-type microbial fuel cell platform without the fluidic system would be more applicable and potentially realizable.
“The biobattery we developed this time was a kind of combined technique of those two; the power duration was significantly enhanced by using solid-state compartments but the device is a form of a battery without complicated energy-intensive fluidic feeding systems that typical microbial fuel cells require.”
This battery is expected to be low-cost, environmentally-friendly by being disposable as well.
