ON Semiconductor – Sensors: Redefining the Status Quo

For quite some time the semiconductor industry has focused on the needs of heightened market segments related to the IoT. ON Semiconductor does in fact offer power management and wireless connectivity, but sensors are what these systems require to interact with any physical elements. The boundaries of what a sensor can do or achieve is constantly being pushed due to a wide availability of devices. Lower power usage, greater capabilities, and improved sensitivity are primary focal points. ON Semiconductor is breaking free from the common application focal points and constraints by achieving an entirely new breed of sensors: sensors that are still designed to make stunning use of these focal areas, but also changing how sensors are thought about and implemented.

ON Semiconductor’s Smart Passive Sensors (SPS)
achieve success by being wireless both in data and power transmission, paper thin in form factor, and entirely disposable. At its core, the Smart Passive Sensor utilizes commonly used radio frequency (RF/RFID) technology and protocols. The SPS family works using innovative and proprietary technology that defines how data and power are collected – technology that has yet to be seen anywhere in the mass market.

Smart Sensor:
The SPS family is designed to sense the common and critical environmental factors such as moisture, temperature, pressure, and proximity. The SPS ‘tag’ contains a single remarkably thin chip. This device is able to manage power, RF connectivity, and sensing capabilities without the need for a microcontroller.

Battery Free:
The SPS family harvests power to function from the power and data transmission emitting from a RF system. There is no more need to worry about standby power consumption, power management, or an I/O control system. All that is needed is to bring a SPS tag near to a RF reader.

Scalable Connectivity:
The SPS family is inexpensive, small, and utilizes breakthrough technology. Ultimately tags can be placed and embedded into anything. What any sensor happy individual will realize is that ON Semiconductor unlocks the ability to collect multiple data points (multiple tags) in any hard to access or space constrained application.

Applications, Thus Far
Sure, this ecosystem of tags and a reader may not be ideal for all applications but this is a limiting thought for the endless possibilities that can be achieved with SPS. Here are a few of our ideas thus far:

Healthcare:
• Place in hospital beds to determine occupant presence
• Place in wristband or patch to monitor condition
• Place in diaper to detect moisture

Farming/Housing:
• Inject under flesh of animal to detect illness and ovulation
• Embed in soil for smart yard watering
• Inset in wall to measure water damage or foundation problems post-construction

Automotive:
• Place in vehicle to determine moisture leaks (soak test)
• Place in seat for occupant presence, number, and weight detection
• Place on tank for fluid level detection

Support
The Tools to Help:

• Plan your ecosystem
• Determine project feasibility
• Proof of concept testing
