Can soft and stretchable materials convert ambient sources of energy into electricity?

Get access to the full version of this article. View access options below. This review highlights various modes of converting ambient sources of energy into electricity using soft and stretchable materials. These mechanical properties are useful for emerging classes of stretchable electronics, e-skins, bio-integrated wearables, and soft robotics.

How smart energy storage has revolutionized portable electronics & electrical vehicles?

Smart energy storage has revolutionized portable electronics and electrical vehicles. The current smart energy storage devices have penetrated into flexible electronic markets at an unprecedented rate.

What is the difference between latent heat storage and sensible heat storage?

Energy is stored and retrieved by cycling the temperature. While latent heat storage utilizes the enthalpy change as the material undergoes a congruent phase transformation, sensible heat storage makes use of the heat capacity of the material as it is cycled between two temperatures to store (and release) energy.

Why do stencil printed batteries have a lower energy storage capacity?

It should be noted that these are the results corresponding to stencil printed batteries, presenting a significantly lower energy storage capacity than that of digitally printed batteries. This is because of the uniform deposition of the electrode and the thickness of the layers (Section S19, Supporting Information ).

Can ultrathin batteries be used in smart cards?

In spite of a showcase of prototype flexible batteries with various chemistries, only ultrathin batteries with mild flexibility and low energy densities are employed in limited fields, including smart cards, micro-electro-mechanical system, and RFID.

What kind of batteries do soft systems use?

Most of the previously mentioned soft systems are either tethered or use traditional rigid batteries. Coin-cell batteries are not desired, as the battery is usually the patch's bulkiest rigid component, several times bigger than the largest microchip in the patch.
