Cricket has always been a sport of small margins — a fraction of a degree on the seam, a slightly higher release point, a half-yard of extra bounce. For most of the sport’s history, those margins were felt rather than measured. That’s changing. Over the past several years, cricket balls embedded with microchips and motion sensors — commonly called “smart balls” — have moved from academic prototypes to genuine training and broadcast tools, and they’re starting to reshape how the game is coached, analyzed, and watched.
This article covers where the technology actually stands, what it can and can’t currently do, and where the genuine uncertainty lies — because not every claim circulating about smart balls this year has held up to scrutiny.
From lab prototype to real product
The idea of instrumenting a cricket ball isn’t new. Academic researchers were testing gyroscopes and accelerometers inside cricket balls as early as the mid-2010s, publishing peer-reviewed work on how embedded sensors could measure spin rate, torque, and a bowler’s “efficiency” — how much of the arm’s rotational force actually converts into ball spin rather than being wasted on wobble (technically called precession). A widely cited 2021 study in the journal Sensors, for instance, used an advanced smart ball sampling motion data at over 800 times per second to profile spin bowlers in detail no external camera system could match.
The technology reached commercial reality in August 2019, when Australian ball manufacturer Kookaburra, in partnership with technology firm SportCor, unveiled the SmartBall at a launch event in London. The design embeds a small chip in the ball’s cork core, using the same construction process as a standard hand-stitched cricket ball, so the ball’s weight, bounce, and feel stay within normal tolerances. The chip measures speed at three points — release, pre-bounce, and post-bounce — and tracks revolutions per minute, data previously available only through expensive external motion-capture rigs.
Cricket Australia responded to the 2019 unveiling with cautious interest rather than immediate adoption, saying any ball used in top-flight competition would need extensive independent testing to confirm it didn’t alter how the ball behaved in play. That measured pace has generally held: smart balls have found their footing in training environments, franchise league experimentation, and biomechanical research, rather than being embedded in balls used for actual first-class or international matches on a Regular basis.
How the sensors actually work
Regardless of manufacturer, the underlying approach is consistent across smart cricket balls: a small sensor package — typically some combination of accelerometer, gyroscope, and sometimes magnetometer — sits in a sealed cavity in the ball’s cork core, wired to transmit data via low-power Bluetooth once the ball is at rest (transmitting mid-flight isn’t necessary, since the sensor logs data continuously and syncs afterward).
From that raw motion data, the ball’s companion software can calculate:
- Speed, measured separately at release, pre-bounce, and post-bounce — more granular than a single radar-gun reading.
- Spin rate and axis, i.e., how fast the ball rotates and around which axis, which matters enormously for both finger-spin and wrist-spin bowlers trying to disguise their deliveries.
- Precession, the wobble in the ball’s spin axis that indicates how efficiently a bowler’s arm action converts into clean rotation rather than wasted motion — this is the metric peer-reviewed research has focused on for talent identification.
- Seam orientation, relevant to swing bowling, where a consistent seam angle at release is a major factor in how much the ball deviates in the air.
What smart balls generally do not do, at least in currently available products, is provide full 3D trajectory mapping independent of external cameras, or reliably detect bat contact (edges) — those functions remain the domain of camera-based systems like Hawk-Eye and audio-based systems like Snickometer/UltraEdge.
Where smart balls are actually being used
Training and coaching is the clearest current use case. Kookaburra’s SmartBall has been trialed in franchise league nets and academy settings, letting bowlers see immediate feedback on speed and revolutions rather than waiting for a coach’s stopwatch or a separate radar unit. For amateur and club-level players, myBall, a Bluetooth-connected smart cricket ball aimed at recreational bowlers, offers a lower-cost way to track delivery speed, swing, and curve through a smartphone app — a genuine democratization of a tool that was, until recently, available only to professional setups.
Biomechanical research is where the most rigorous work has happened. Studies using high-sample-rate smart balls have found measurable differences in bowling efficiency between finger-spin and wrist-spin deliveries, and between topspin and backspin variations — data that’s directly useful for coaches working with developing spinners, since it can flag technical inefficiencies before they show up as inconsistent results on the field.
Broadcast and fan engagement is the area most likely to expand next. A chip that can report exact revolutions per minute or precise release-point data is a natural fit for the graphics packages broadcasters already build around ball-tracking technology, even if the smart ball itself isn’t yet embedded in balls used in official international matches.
What smart balls are not: the IPL example
It’s worth clearing up a common point of confusion, because it appeared in earlier coverage of this topic (including on this site): the Indian Premier League’s 2025 expansion of automated no-ball and wide-ball decisions does not use an embedded smart ball. It runs entirely on Hawk-Eye, a network of external high-speed cameras that tracks the ball’s flight and compares it against a stored database of each batter’s measured height. The IPL introduced Hawk-Eye-based waist-height no-ball detection in 2024 and expanded it in 2025 to cover head-height wides and off-side wide calls as well, using the same camera infrastructure Hawk-Eye already provides for DRS reviews.
This is an important distinction: camera-based systems like Hawk-Eye and ball-embedded sensor systems like Kookaburra’s SmartBall are two separate technological approaches to a similar problem — getting more objective, ball-flight data into the game. They’re often discussed interchangeably in casual coverage, but they don’t currently overlap. No major international competition, including the IPL, currently uses an embedded smart ball for live match officiating.
The real benefits
Where the technology has been tested and used, the benefits are genuine:
- Objective feedback for bowlers. Instead of relying on a coach’s eye or a basic speed gun, bowlers can see precise, repeatable data on their own deliveries and track changes over a training block.
- Better talent identification for spin bowling. The precession and efficiency metrics developed through academic research give coaches a way to spot promising young spinners whose raw results don’t yet reflect their underlying technique.
- Accessible entry point for amateurs. Products like myBall bring meaningful bowling analytics to club and school-level cricketers at a fraction of the cost of professional motion-capture setups.
- A foundation for richer broadcasts. As the technology matures, viewers could see live revolutions-per-minute or precession data overlaid during a match, similar to how pitch-speed and spin-rate data already appear in baseball broadcasts.

The real challenges
The obstacles are just as real as the benefits, and worth being honest about:
- Durability and cost. Embedding electronics in a ball that’s repeatedly struck at high velocity, bowled at speed, and used across dozens of overs is a genuine engineering challenge, and these balls cost meaningfully more than standard match balls.
- Regulatory caution. Cricket’s governing bodies have been deliberately slow to approve smart balls for official competition, wanting assurance that the embedded electronics don’t measurably change how the ball behaves — a reasonable concern given how sensitive bowlers are to even minor variations in a ball’s feel and seam.
- Format-specific engineering. Women’s cricket uses a lighter ball (approximately 142g versus 155–163g for men’s cricket), which means sensor packages designed for one format may need separate engineering for the other, rather than a single one-size solution.
- The human-element debate. Some in the cricket community have raised a fair question: does exhaustively quantifying every aspect of a delivery risk stripping away some of the instinct and artistry that make bowling distinctive? This isn’t a technical problem to solve so much as a cultural conversation the sport will keep having as the technology matures.
What’s realistic to expect next
Based on where the technology and its adoption actually stand, the most plausible near-term developments are incremental rather than revolutionary: continued refinement of training and coaching tools, broader adoption of camera-based systems like Hawk-Eye for officiating (since that technology is already proven and doesn’t require modifying the match ball itself), and gradual expansion of affordable consumer products like myBall into more markets. A full switch to smart-ball-based officiating in top-flight cricket, or wholesale replacement of on-field umpires, remains speculative rather than something with a concrete timeline behind it.
Frequently asked questions
What is a smart cricket ball?
A cricket ball with a small sensor package — typically an accelerometer and gyroscope — embedded in its cork core, which measures speed, spin rate, and other delivery metrics without meaningfully changing the ball’s weight or feel. Kookaburra’s SmartBall, launched in 2019, was the first commercially unveiled version.
Does the IPL use smart balls?
No. The IPL’s automated no-ball and wide-ball decisions run on Hawk-Eye, an external camera-based tracking system, not an embedded ball sensor. This is a common point of confusion, since both technologies aim to add objective ball-flight data to the game.
Can amateur players buy a smart cricket ball?
Yes. Products like myBall offer Bluetooth-connected smart balls aimed at club and recreational players, with companion smartphone apps for tracking delivery speed and swing.
Are smart balls used in professional matches?
Not yet for live officiating in major competitions. They’ve been trialed in training environments and used extensively in academic biomechanical research, but no major international competition currently uses an embedded smart ball to officiate matches.
Will smart balls replace umpires?
Not on any confirmed timeline. Camera-based systems like Hawk-Eye are far more advanced in officiating applications right now than embedded ball sensors are.
The bottom line
Smart cricket balls are a real, useful technology — not a marketing gimmick — but the current state of the art is more modest than some 2025 coverage suggested. The genuine progress is in training, coaching, and biomechanical research, where Kookaburra’s SmartBall and consumer products like myBall are already delivering value. The more dramatic claims about live-match officiating and mysterious new manufacturers deserve the same scrutiny any other emerging-tech story gets: check the source, separate confirmed products from rumored ones, and don’t confuse a camera system with a chip in the ball.
