- •
The hydrogel containing cellulose was capable of swelling and deswelling in water without breaking.
- •
Swelling ratio, force of expansion and moisture were analyzed.
- •
The hydrogel was used to operate a valve and to control soil irrigation.
- •
An autonomous actuator capable of controlling soil moisture was developed.
- •
The actuator response was very stable for four months.
