1. A hydrogel sensor device, comprising:
a crosslinked hydrogel body which changes in volume in response to an environmental stimulus;
a support post positioned to mechanically support the crosslinked hydrogel body during the change in volume, wherein the crosslinked hydrogel body is unbounded and the crosslinked hydrogel body circumscribes the support post; and
a sensor positioned to detect the change in volume in the crosslinked hydrogel body, wherein the sensor comprises an optical detector, a magnetometer, an ultrasonic detector, an electrical inductor, or a combination thereof.
