PRESS: Manufacturing in Focus article: Nikola Labs Brings Predictive Maintenance into the Future of Industry
Nikola Labs (recently rebranded as AssetWatch®) approached Nottingham Spirk to develop the hardware needed for its PfM Sensor System. The Vero predictive maintenance system consists of sensors and transponders and IoT cloud platform. The sensors monitor the temperature and vibrations of heavy machinery and relay data back to the transponders to help staff anticipate equipment failure. The sensors are also equipped with tiny, proprietary INDRA chips, which convert radio frequency (RF) energy from the transponders into direct current power. This means more sensors can be used in more hard-to-reach places because there is no need to schedule downtime for battery replacement (“a maintenance program for my maintenance program,” as one factory owner put it).
The technology was developed at The Ohio State University by Dr. Chi-Chih Chen, who worked with Texas Instruments and Skyworks Solutions to reduce the chip size. Nikola Labs then turned to Nottingham Spirk for help with the product design and building critical waterproof housings and mountings. NS worked fast and responded in time to prove value in the field. We also helped Nikola develop the proximity sensor, which shuts off the RF flow when obstructed, for instance by a person walking past it.
