In a battery-powered, wireless sensing node, the biggest energy consumer typically is the RF transmitter. The transceiver should have extremely low power in active, wait and even sleep modes. A one-second snapshot of the current consumption in the various portions of the transmission cycle shows the current draw of 15 mA for the 7.5-ms receive […]

How does a finger unlock a door?
At Sensor Expo 2019, Marcia Ratton from TDK InvenSense demonstrates how the UltraPrint Sensor (TCFS-3000) precisely identifies a finger print. Integrated into a door lock, the image from the sensor is displayed on a screen to demonstrate the clarity and details of the image. The ultrasonic fingerprint imaging uses proprietary InvenSense, a TDK Group company, […]
How can an RTC feature stabilize an image sensor’s output?
At Sensors Expo 2019 in San Jose, CA, Sahil Choudhary, a product marketing manager at InvenSense, demonstrates how the real-time clock (RTC) feature in his company’s 6-axis (accelerometer and gyroscope) sensors provides accuracy and stabilization for critical imaging applications. For a specific device frequency, say 10 Hz, the RTC input ensures that the 10 Hz […]

Sensors on the board include: • […]
Tracking Motion in Portable Products -1
Mobile devices, wearable sensors, fitness watches and remote health monitoring appliances are among the products that can take advantage of advanced motion sensing technology. At the 2013 International CES, several companies announced new products to address these applications. InvenSense MPU-9250, in a 3x3x1mm QFN package, is a fully-integrated 9-axis device that includes a gyroscope, accelerometer […]
Nine-Axis MEMS Motion Sensing
At the 2012 International CES (Consumer Electronics Show) in Las Vegas, David Borison of InvenSense demonstrates the capabilities of nine-axis motion sensing using the company’s newly introduced MPU-9150 nine-axis (gyro + accelerometer + compass) MEMS MotionTracking device. The multi-axis sensor incorporates MotionFusion and run-time firmware that simplifies motion sensing in end products. To further simply […]
Smallest Sensor Week: Dual-Axis Gyroscopes Boast Smallest Packaging
With a 3 x 3 x 0.75-mm form factor, InvenSense Inc. lays claim to the world’s smallest dual-axis gyroscopes. Targeting optical image stabilization (OIS) in smartphones, the IDG-2020 is an x-y (roll and pitch) and the IXZ-2020 is an x-z (roll and yaw) dual-axis MEMS gyroscope. Features in the gyroscopes designed specifically for OIS requirements […]
Highly Integrated MEMS-Based Motion Sensing
Motion sensing is at the heart of several new features in consumer products including cell phone, tablet PCs and games. InvenSense has been a major player in these applications but its newest product family makes motion sensing even easier to design and manufacturer. MPU-6000 product family integrates a 3-axis gyroscope and a 3-axis accelerometer on […]
