Chatting on phone drains its battery, but in future ,all the talk time could actually be used to boosts its power.
Researchers from Canada have created a chin strap that harvest energy from jaw movements including talking and chewing
It is hoped that the device could be used to power electronic devices such as hearing aids , cochlear implants, and even phones .
The chin strap is made from a smart material known as PFC ,PFC is a type of piezoelectric material made of integrated electrodes , and an adhesive polymer matrix.
The material is able to produce an electric charge when it stretches and is subjected to mechanical stress.
In their study researchers , from Sonomax-ETS Industrial Research Chair in In -ear Technologies (CRITIAS) in Montreal, Canada , created an energy harvesting strap made from a single layer of PFC and attach it to a pair of ear muffs using a pair of elastic side straps .
To ensure maximum performance , the chin strap was fitted snugly to the user , so when the use's jaw moved it caused the strap stretch .
Jaw movements proved to be one of the most promising candidates for generating power ,electricity from human body movement , with researchers estimating that an average of around seven micro watt of power could be generated from chewing during meals alone.
To test the performance of the device ,the subject was asked to chew gum for 60 sec while wearing the head -mounted device .
The maximum amount of power that could be harvested from the jaw movement was around 18 megawatt , but researchers claim that a realistic be output is closer to 10 micro watts.
This is still a fraction of energy used in a typical phone charger , which use between 10 to 16 watt per day- but the strap is still in an experimental phase.
To sum up -

To sum up -
- The chin strap is made from a smart piezoelectric material known as PFC .
- PFC is made up of integrated electrodes and adhesive polymers.
- It produce electric charge when stretches and is subjected to stress.
- The maximum amount of power harvested was 18 micro-watts
- But researchers are working on increasing this output significantly.
