If these moisture-sucking additives do their job while the devices are off, then maybe the heat the technology generates while powered on can remove the moisture the desiccants soaked up and keep them working for longer, the team reasoned.
Silica gels might not respond best to heat from an electronic device, they found, but other desiccants might pull this trick off. Researchers are constantly experimenting with silica gel packets and other desiccants to see what the materials can accomplish.
A team of microbiologists, for example, tucked samples of the Streptococcus pneumoniae bacteria into individual packets and found that silica gel did a good job of keeping the potential pathogen alive during transit between labs.
Researchers are happy to rework the silica format, too. For scenarios where manufacturers need thinner or more dispersed water-removal technology, engineers developed thin sheets and powdered versions of silica gel. Aerogels — silica variants that are a kind of solid foam — make for good insulation in boots and on a Mars rover. Despite silica gel's versatility, one way not to use the material is as a snack.
Truthfully, silica gel is nontoxic. The biggest issue, according to the Illinois Poison Center, is choking on the packet itself. Since there can be confusion sometimes over what exactly is in the packet, the Arizona Poison and Drug Information Center recommends calling poison control if someone swallows a desiccant packet, just in case.

Most Popular Types of Silica Gel Desiccant Silica gel is most commonly recognized in packet form, but it also comes in bulk.
Here are the most popular types of silica gel and packaging: White Silica Gel bulk : High capacity for moisture and can also adsorb C12, C02, gasoline-range hydrocarbons, HC1, sulfur and nitrogen compounds, and other substances. Blue Indicating Silica Gel bulk : Similar to white silica but changes from blue to purple to pink as moisture is adsorbed. Silica Gel Desiccant Unit Packs Tyvek bulk : Individual units for all size packaging Silica Gel Desiccant Packets : Individual packets for all kinds of consumer products from medicines to electronics to shoeboxes.
Common silica uses in bulk: Product packaging clothing, medicine, electronics, fresh produce, etc. Humidity control systems residential, commercial, and industrial Manufacturing systems prevent mechanical failure from moisture Document protection libraries, museums, stored files, etc. Silica Gel Suppliers Delta Adsorbents has been distributing silica gels and other humidity control solutions since Activated Alumina.
