In recent years, scientists have found it possible to harness the
excess heat given off the human body to use as a source of power.
Researchers at KAIST Research University in South Korea have
developed a thermoelectric generator that is encased in glass
fabric. The fabric is incredibly flexible, light, and allows for a
high power output, which is a necessity for the practicality of
using such generators with electric devices.
Electricity is generated through a temperature difference between
the air and a person’s skin, and since the head generates the most
heat, it is an ideal spot for the thermoelectric generator to
function. As the generator requires contact with the skin, it must
be paired with a behind-the-ear version of a hearing aid, as other
models are inserted within the ear and don’t have reliable access to
the cooler ambient air.
Heat Utilizing Hearing Aids use the power generated from the body’s
surplus heat to reverse the discharge of the battery, and to make
the cell’s charge full again. As the batteries of the hearing aid do
not require removal in order to charge, the wearer does not run the
risk of losing them. This also applies to users who may lack the
dexterity to handle small parts, such as the elderly, who often
experience hearing loss as a part of aging. With the original
batteries capable of supporting the system long-term on account of
the integrated charging aspect, less batteries need to be produced,
therefore reducing the output of harmful greenhouse gases seen
during the manufacturing process.
Regardless of how they function, all hearing aids have the same
purpose: to help enhance the hearing of those in need. With Heat
Utilizing Hearing Aids, the wearer is getting the same benefit—with
the convenience of a reliable charge.
Pictured above is the Korean Glass Fabric. This flexible, light weight material will be placed against the skin and the thermoelectric generator will charge the hearing aid battery. Heat Utilizing Hearing aids are packed with benefits, without any added discomfort to heaing aid users!
