<p>Scientists have developed a wireless charging device that can be fitted under the skin to charge the bioelectronic devices in the body. The product has shown promising results when tested in rodents. If a similar level of success is seen in humans, it would mean medical implants can get rid of the clunky batteries and wiring that come with them.</p>

<h2><strong>Why the device is needed?</strong></h2>

<p>Wireless charging devices are required due to the fact that most bioelectronic devices, including sensors and drug-delivery systems, are limited by the capacity of onboard batteries.</p>

<p>If these systems are attached to an external source of power, the risk of infection getting spread increases significantly.</p>

<p>So, scientists came up with the idea of developing these flexible, under-the-skin chips. According to a research paper published in the journal Science Advances, these chips are biodegradable and can adapt to the shape of tissue during a procedure.</p>

<p>"Our prototyped power supply system represents an important step forward in advancing a wide range of biodegradable implantable medical devices with its potential to provide effective and reliable energy solutions," study co-author Wei Lan, a professor of electronics in the School of Physical Science and Technology at Lanzhou University in China, was quoted as saying by Live Science.</p>

<h2><strong>How does the wireless device work?</strong></h2>

<p>Diverging from batteries that store energy chemically, these supercapacitors store power in the form of electrical energy.&nbsp;</p>

<p>Despite holding less energy per unit compared to batteries, they boast a high power density, allowing for substantial energy discharge.&nbsp;</p>
