A International Researcher Team, Affiliate has UNIST introduced an innovative portable technology that turns your skin into a speaker.


This advance has been led by Professor Hyunhyub KB at the School of Energy and Chemical Engineering at UNIST. Created In Part To Help the Non-Hearing Impaired of Speech, New Technology More You Can EXPLORE a Fund for Various Potential Applications, such as Portable IO Sensors and Compatible Health Care Devices.

In the study, the research team has developed ultra-thin, transparent non-conductive hybrid nanomembranes with nanoscale thicknesses consisting of a silver nanowire matrix in an orthogonal polymer-embedded matrix. They, THEN, demonstrated their nanomembrane by converting it into a speaker that can be connected with almost anything to produce sounds. Researchers also introduced a similar device that acts as a microphone that can be connected has smart phones do not unlock computers for voice activated security systems.

The nanomembranes (NM) layers their molecular separation with Thin Thickness of the UN has nanoscale. The NM Polymers have attracted considerable attention due to excellent advantages of the SUS, such as extreme flexibility, ultralight weight and excellent adhesion, is that if they can join a directly almost any area. However, get rid of it pleasantly and electrically electrical conductivity.

The Research team has solved THESE Problems through a red incorporation of silver nanowires within a nanometer-based polymer. This! It has allowed the demonstration of a loudspeaker Microphone there are imperceptible connectable has skin.

"Our ultra-thin NM hybrids are transparent conductive facilitating contact swindlers curvilinear areas that meet there Sin Dynamics or Cracks Ruptures", given The Saewon Kang doctroral Program of Energy and Chemical Engineering at UNIST, the first author of the study.

AND ANADE "these Layers its Able to DETECT there produced voice vibrations by voltage triboelectric signals corresponding to sounds that could be further explored for diverse potential applications, as input / output sound devices".

Using the NM hybrids, the Research and Fabrication team Microphones Speakers NM connectable by the skin that discreetly Serious in DUE Appearance one do s capacity and excellent transparency compatible contact. These Portable Speakers there Microphones its Fine Like the paper, But STILL its CAPACIES of Making sound signals.

"The biggest advance of our research is the development of ultra-thin, transparent, non-conductive hybrid nanomembranes with a nanoscale UN Thickness of less than 100 nanometers", given Professor KB. "These Excellent Optical Properties, Mechanical Electrical nanometers allow the demonstration of a microphone speaker are not connectable imperceptible has skin."

NM Loudspeakers can be connected by the skin They work by emitting a thermoacoustic sound through the oscillation induced by the temperature of the surrounding area. The Joule Periodic Heating that When An electrical current passes through a heat conductor leads and conducts a These temperature oscillations. It has attracted an attention for being considerable stretchable, connectable transparent loudspeaker has no skin.

The Microphones Wearable their Sensors, Connected to the Neck of a conversation INCLUDED to perceive the voice of the strings Vibration. This sensor operates by converting the friction force generated by the oscillation of transparent conductive nanofiber into electric Energia. For the Operation of the Microphone, the hybrid nanomembrane is inserted between elastic films with small patterns to detect precision that with the sound and the voice strings vibration as a function of a triboelectric voltage that the results of the search of the swindles CONTACT the elastic films .

"For Commercial Applications, Mechanical Durability of Nanomebranes and Performance and Speaker Microphone Should Be Improved: Even More" Given Professor KB.
