1 Overview
There are various types of accelerometers available with different measurement ranges, thresholds,
precision, and accuracy, but in general, they all convert mechanical vibration into an electrical signal,
which can then be converted to acceleration.
The DRV-ACC16-EVM can measure acceleration up to 16 g(“g” is the acceleration due to Earth’s gravity
or 9.81 m/s2). The EVM converts the acceleration from mechanical movement to mV at a rate of 57 mVpeak
per gpeak. This means that every 57 millivolts of peak voltage equals 1 gof peak acceleration and 114
mVpeak equals 2 g’s of peak acceleration.
1.1 Required Equipment and Materials

3 Converting Voltage to Acceleration
The output voltage of the three accelerometer channels has a DC offset of 1.5 V at 0 g. The channels of
the DRV-ACC16-EVM can be AC coupled to only show changes in acceleration. This is recommended for
measuring the acceleration of haptic systems.
Figure 5. AC-Coupled Accelerometer
To calculate the acceleration, take the peak voltage of a single accelerometer output and divide by 57 mV.
Every 57 mV of peak voltage corresponds to 1 gof peak acceleration.

4 Determining the Axis of Vibration
The orientation of the accelerometer can be determined by the 3-axis label on the small accelerometer
board. The direction of the arrows corresponds to the axis which the acceleration is measured. The Z-
direction is measured normal to, or coming out of, the board.
Figure 7. Acceleration Axis
For haptic applications, the axis of vibration is determined by the motion of the actuator. Take for example
a DC motor that spins around the X axis and creates force in the Y and Z axes. In this case, measure
vibration by connecting to the Y and Z test points of the accelerometer.
The axis of vibration can often be found in the actuator datasheet; if not, the axis is usually easily
determined by measuring all axes and finding the axis with the highest acceleration. Below are example
diagrams of ERM, LRA, and Piezo actuators and their axes of vibration.
NOTE: Not all actuators will have these same axes of vibration.
4.1 Eccentric Rotating Mass
The ERM motor in Figure 8 spins around the X axis and produces rotational vibration in the YZ plane.
Acceleration can be observed on the Y and Z accelerometer channels.

www.ti.com Mounting Guidelines
5 Mounting Guidelines
In general, actuators should be mounted in an application using a combination of adhesion and
compression. The adhesive ensures the actuator remains in place and the compression mitigates
manufacturing tolerances and ensures that the vibration is transferred to the body of the device.
Figure 14. LRA Mounting Stack Up
Actuators are often mounted using an adhesive transfer tape from 3M. This double-sided tape is very
strong and intended to withstand a long lifetime of vibration. Many actuator manufacturers provide the
option to include the adhesive tape on the actuator for production builds.
Table 4. Adhesive Transfer Tape for Mounting Actuators
Part Number Manufacturer Description
3-5-468MP 3M Adhesive transfer tape
Alternatively, some ERM and LRA actuators can be soldered to the PCB board directly to ensure long
lasting vibration performance; however, care must be taken to ensure that vibration is transferred from the
PCB to the chassis of the device.
6 Mounting an Actuator for Testing
The acceleration of an actuator often needs to be measured outside of the final system or application to
compare actuator strengths, run life-tests, or create haptic effects. The best way to measure acceleration
is to mount the actuator on a fixture that has similar mass to the final application. We call this a haptic test
fixture. To do this:
1. Create a test fixture that has a similar size and weight as the final application. An aluminum or similar
material block works well for most applications.
2. Place the actuator in a similar location as it would appear in the final application and attach it to the
mass using strong adhesive tape, epoxy, or glue.
3. Place the test fixture on a material that can isolate the vibration such as a piece of foam or a silicone
gel. The mechanical isolation prevents rattling and transferring vibration to the table. Test the material
and make sure it roughly mimics the final application environment.
4. Place the accelerometer board on the fixture using the adhesive tape, near the actuator and begin
measuring.
To measure the acceleration of an actuator for use inside a smartphone, place the actuator on a 100 g
block that has a similar size and shape as the phone. Next, place the block on a piece of packing or ESD
foam to represent a hand, which is where a phone is normally held. Finally, measure the acceleration of
the block on the foam and compare it to when a person holds it in their hand.
