00:00:02.963 --> 00:00:05.535
NVE is extending its leadership
with the launch of

00:00:05.535 --> 00:00:08.099
an ultrasensitive, ultraminiature

00:00:08.099 --> 00:00:10.972
Wafer Level Chip-Scale magnetometer.

00:00:11.287 --> 00:00:17.854
As robots get smaller and more precise,
they need smaller, more precise sensors.

00:00:18.317 --> 00:00:20.142
We have a tiny demonstration,

00:00:20.301 --> 00:00:24.377
befitting the world's smallest
TMR magnetometer sensor.

00:00:24.798 --> 00:00:28.016
The sensor is just 0.55 millimeters square.

00:00:28.824 --> 00:00:35.341
The demo also uses a tiny 2 mm diameter magnet,
on an itsy-bitsy stepper motor.

00:00:36.133 --> 00:00:42.616
It's driven by a small stepper driver board
and controlled by an Arduino Pro Micro.

00:00:43.172 --> 00:00:48.963
A small OLED display shows the sensor's
remarkable sensitivity and range.

00:00:48.963 --> 00:00:54.606
The demo provides a 3:1 field range
over 5 mm of travel.

00:01:05.287 --> 00:01:09.154
We can also display a graph,

00:01:12.622 --> 00:01:18.193
which shows the sensor's
excellent repeatability and low hysteresis.

00:01:18.916 --> 00:01:20.804
As the physics predicts,

00:01:20.804 --> 00:01:23.745
the field drops off
with the cube of distance.

00:01:24.530 --> 00:01:31.628
But we can easily detect
the tiny magnet 10 mm away.

00:01:36.586 --> 00:01:40.217
The splash screen summarizes the sensor features,

00:01:41.868 --> 00:01:43.975
including a wide linear range;

00:01:44.455 --> 00:01:46.675
Ultrahigh sensitivity;

00:01:47.063 --> 00:01:48.765
and small size.

00:01:49.733 --> 00:01:52.337
This is the wiring diagram.

00:01:54.534 --> 00:01:58.470
These are the tiny things
we used for this demo:

00:02:00.000 --> 00:02:01.401
Our TMR sensors come in

00:02:01.401 --> 00:02:16.920
2.5 mm, 1.1 mm, or the new 0.55 mm
Wafer Level Chip-Scale Package.
