A new pressure sensitive capsule for monitoring rumen activity has been developed. Surgery on the animal is not required for introducing the unit because it is small enough to be placed in the rumen using a stomach tube. The unit will transmit for several weeks and uses an inexpensive, commercially available pressure transducer as a sensor.

一种用于监测瘤胃活动的新型压敏胶囊已研制出来。由于该装置体积小，可用胃管将其放入瘤胃，因此无需对动物进行手术来植入该装置。该装置能传输数周数据，并使用一种廉价的、可在市场上买到的压力传感器作为传感器。
