Horse trainer Annemarie O'Brien set up Equimetrics to create a health monitor for horses.

Horse trainer Annemarie O’Brien lost one of her most promising horses to colic a few years ago and since then she has been developing technology to monitor equine health.

She set up the company Equimetrics to create a health monitor for horses that measures heart rate, temperature, sweat, respiration, movement and activity. The monitor can also do a 24-hour ECG and send the results to an app.
