The COVID-19 pandemic has highlighted the importance of harnessing and leveraging digital technology for remote patient tracking. We see a need for more robust disease identification and control of patient and public wellbeing, which might be assisted by wearable devices, as existing viral testing and vaccines are slow to develop. COVID-19, like other viral illnesses, is associated with several physiological changes that can be tracked with wearable biosensors. Numerous cardiac rhythm indicators, such as Heart Rate (HR), Heart Rate Variability (HRV), Blood-volume Saturation, and Respiration Rate (RR), might serve as possible markers of COVID-19 infection and are already measured by smart wearables that use PPG technology. Companies are developing innovative technologies to facilitate healthcare staff in reducing transmission risks while still increasing clinician and patient safety. For instance, in May 2019, Masimo received FDA clearance for its Tetherless Radius PPG biosensors that aid the placement of point-of-care monitors outside a patient’s room safeguarding constant monitoring from a distance.

The increasing prevalence of cardiovascular disorders is majorly expected to propel the growth of the market for PPG biosensors over the estimated study period. For instance, according to the American Heart Association, Inc., at least 48.0% of U.S. adults have some form of cardiovascular disease, and by 2035, more than 130 million adults, or 45.1% of the U.S. population is estimated to have some CVD. Thereby, the association of this technique with advances in technology seems to proportionate the detection of cardiopathies rapidly, enhance medical treatment with remote control and surveillance of the patient in a healthcare setting, and minimize the number of deaths caused by cardiovascular diseases.

PPG is a non-invasive, inexpensive technique as compared to the ECG biosensors and also it can be easily incorporated on several sites such as a finger, toe, ear, wrist, chest, and head for measuring the signal. The non-invasive PPG technique for measuring SpO2 and HR is widely used in personal handheld devices and clinical pulse oximetry due to its simplicity and ability to perform continuous readings. It is considered a compact, low-cost device with a basic application that is also non-invasive and applicable in a variety of settings. In addition to the previously stated characteristics, the development of signal processing algorithms adds robustness that contributes to the advancement of this technology. Hence, owing to several advantages offered by PPG, the demand for these biosensors will surge in forthcoming years, leading to market growth.

Product Insights

The smartwatches segment dominated the market for PPG biosensors and held the largest revenue share of 41.9% in 2020. The segment is expected to witness a considerable growth rate over the forecast period. PPG biosensors have lately been extensively used in consumer smartwatches to monitor user health conditions during sport, sleep, and everyday activities. According to the Consumer Technology Association, in 2019, 20.1 million units of smartwatches were sold in the U.S. The majority of such products, including the Apple Watch, Fitbit, Garmin, and many other smartwatches have heart rate monitors that use Photoplethysmography (PPG). Changes in the blood flow flowing through the wrist caused by the peripheral pulse are monitored using light beams and light-sensitive biosensors on the smartwatch to produce a PPG, which is then used to determine the heart rate.

Furthermore, industry players' ongoing technological advances are fueling the development of smartwatches, as they are technical devices that necessitate continuous R&D for various features. Recently in April 2021, Amazfit Bip U Pro and BOAT Xplorer have been launched in India. The smartwatches have PPG bio-tracking optical sensors that continuously monitor heart rate.

The pulse oximeters segment is anticipated to witness the fastest growth rate in the market for PPG biosensors over the forecast period. The primary application of dual-wavelength PPG is pulse oximetry, which calculates arterial Oxygen Saturation (SpO2) noninvasively. Adoption of smart, medical-grade pulse oximeters remains strong, but new markets for lower-cost, commoditized products may emerge in the future. In May 2019, Radius PPG, a tetherless sensor solution operated by Masimo SET that represented a major advance in patient tracking, received FDA 510(k) clearance. Radius PPG eliminates the need for a cabled attachment to a pulse oximetry monitor, enabling patients to travel independently and safely while still being constantly and accurately monitored. Lately, in April 2021, Health-tech startup MFine launched 'MFine Pulse', an application-based SPO2 monitoring device that might aid people to monitor their oxygen saturation levels through their smartphones. Furthermore, the rising prevalence of cardiovascular diseases and a spike in the geriatric population, as well as the increasing demand for wearable monitoring devices, are driving the growth of the smart pulse oximeters segment.

Application Insights

The heart rate monitoring segment dominated the market for PPG biosensors and held the largest revenue share of 39.9% in 2020 and is anticipated to witness a considerable growth rate over the forecast period. Smart wearables with heart rate monitor mostly use PPG. Cardiovascular Disease (CVD) is the primary cause of death in the world and patients suffering from CVD require continual monitoring. According to the World Health Organization (WHO), CVD is the leading cause of death worldwide, with nearly 30 million people suffering from a heart attack or stroke each year. According to the American Heart Association, almost half of all adults in the United States have a kind of cardiovascular disease. More than 130 million adults, or 45.1% of the U.S. population, are expected to have CVD by 2035.

Moreover, there has been an uptick in the prevalence of diseases such as hypertension, diabetes, dyslipidemia, and obesity as a result of lifestyle changes, both of which lead to the increasing incidence of CVD around the world. Pre-monitoring and pre-diagnosis might eliminate the majority of CVDs. Arrhythmias, which are defects in the heart's activity, can also be avoided with early detection. As a result, demand for PPG biosensors is rising, as these devices will help rescue patients who are at high risk of cardiac arrest.

Global PPG biosensors market share, by application, 2020 (%)

The blood-oxygen saturation segment is anticipated to witness a considerable growth rate in the market for PPG biosensors over the forecast period. Photoplethysmography is an optical technique for measuring changes in blood flow. Pulse oximetry, in which the arterial Oxygen Saturation (SpO2) is measured noninvasively, is the most common use of dual-wavelength PPG. Estimating relative variations in hemoglobin concentrations from the same PPG waveforms that are used to calculate SpO2 and heart rate might well be a useful addition, allowing photoplethysmography's variety of applications to be expanded further.

Several smartphone-connected handhelds or wearable PPG biosensors of HR and heart rhythm from the finger, face, and wrist have recently been authorized. In Feb 2020, Maxim Integrated Products announced its novel wrist-based system the MAXREFDES103, specifically designed for the continuous monitoring of blood oxygen saturation (SpO2) levels and heart-rate variability (HRV). Also, in Sept 2020, Huami launched Amazfit GTR 2 and GTS 2, facilitating blood oxygen level trackers. The Amazfit GTR 2 is fortified with the latest BioTracker 2 PPG optical sensor that allows it to check the blood oxygen saturation levels in conjunction with mapping the user’s heart rate. Such advancements will contribute to the extensive application of PPG in measuring blood-oxygen saturation levels, thus leading to the growth of the market for PPG biosensors.

Regional Insights

North America dominated the PPG biosensors market in 2020 and accounted for the largest revenue share of 39.8%. The region is expected to witness a considerable growth rate of 12.4% over the forecast period.
