Inertia sensors
ICC are looking at a device which may ultimately banish the art of chucking as a whole. Although this is still in imagination stage, but building such a unique device within the next decade is certainly possible.
What are Inertia sensors? It’s actually a complex engineering tool that works on a more complex principle of physics, an inertia sensor is a device that can sense a definite change in spatial position of something. A detailed understanding would be possible if one knows the working of accelerometers, MEMS gyroscopes, and inertial gyroscopes.
These days a bowler suspected of illegal action is sent to biomechanics lab. The main problem is this test is only possible in the labs, and being aware early on that he will have to face a test, the bowler might correct his action during the test to gain a clean chit and go back to his business repeating the same illegal action. Real-time sensing is, that’s why an absolute necessity to scrap chucking entirely from cricket.
