Medical & Health

In modern medicine, medical sensors actually replace the doctor's sensory organs in diagnosis and treating instruments and play an extended role. It has become a key technology that restricts the development of high-level advanced medical equipment. The innovation of medical sensor technology will promote the faster development of modern clinical medicine. There are variety of sensors involved in medical use, such as motion sensor, flow sensor, temperature sensor, speed sensor, pressure sensor, etc. Take pressure sensor as an example, there are metal strain gauge pressure sensors, semiconductor pressure sensors, capacitive pressure sensors and all other sensors. And temperature sensors include those based on principles of thermistors, thermocouples and thermopiles, etc.

1.Forehead Thermometer

Due to the global ranging impact from COVID-19 epidemic, home use thermometers become more popular. The forehead thermometer is gloriously increasing due to its convenient and quick measuring, no laser damage to the eyes, and no need to touch the skin avoiding cross infection. It’s already used in home, hotels, enterprises, clinics, and can also be used in comprehensive places such as large hospitals, schools, customs, airports, etc. Now it has been one of the main products to measure body temperature. Winsen’s infrared thermopile sensor is based on latest MEMS technology for forehead and ear thermometers.

• Fast response
• High precision
• Strong anti-interference ability

2.Ventilator, oximeter

The number of people infected with the Covid-19 in the world has exceeded 630 million, and the epidemic has spread to all corners of the world. Pulmonary fibrosis in severe patients leads to difficulty breathing, and critically ill patients cannot even breathe on their own. As one of the main medical devices for treatment, the ventilator can prevent respiratory failure and reduce syndrome. The air flow sensor is one of the key components of the ventilator. It can automatically adjust the ventilator by detecting the gas flow and converting it into other output signals.

Pulse oximeters are most commonly used by people with respiratory conditions and sometimes by athletes and pilots who must monitor blood oxygen levels. They are primarily used for clinical measurement and surveillance, but may also be used at home for certain populations. The Covid-19 pneumonia is very demonic that some patients with very low blood oxygen levels have not been aware of the seriousness of their condition. So some doctors, especially in the United States, recommend using a pulse oximeter for home monitoring

• Latest MEMS sensor chip technology
• Accurate measurement of very small flow
• Fully calibrated and temperature compensated

3.Oral breath test

Fresh breath will make people feel pleasant and more confident. If there is bad breath, it will affect daily communication, and it will also make people feel embarrassed and inferior. Some people have serious bad breath, but they do not realize the problem and have no idea to seek treatment. Studies have shown that about 80% to 90% oral odors are caused by oral diseases, mainly caused by periodontal disease, infection complicated by oral mucosal lesions, and food residues. The hallmark gases of oral disease odor often contain sulfur. The main characteristic gases are hydrogen sulfide (H2S) and methyl mercaptan (CH3SH). The hallmark gas in the mouth of diabetic patients is acetone. If we want to know the cause of the patient's bad breath, then It is necessary to detect the characteristic gas with corresponding sensor, so as to provide a basis for the diagnosis.

• Low power consumption
• Long work life
• Low cost

4.Flexible pressure

Flexible pressure sensors have a wide range of applications in many ways. For example, it can be used in wearable electronic devices to monitor physiological signals such as pulse and heartbeat of the human body. At the same time, it is also an important component of the robot's tactile perception ability. Attaching flexible pressure sensors to the surface of prosthetics is expected to restore the sense of touch to people with physical disabilities. It can also combine sensors and clothing, which can not only monitor the health and movement signals of the human body in real time, but also simplify the use process.

• Flexible pressure sensor 
• Long life span
• Low cost

5.Disinfecting products

As an efficient disinfectant, ozone has superior advantage that it can decomposes itself into oxygen and does not produce residue pollutants compared with other commonly used disinfectants. And it does not require ventilation after disinfection. Therefore, ozone O3 is widely used in many areas like food process, medical, air quality monitoring, etc. But it’s very important to control the O3 concentration and leakage because high concentration will cause human poisoning and environmental pollution. Winsen ozone sensor can be integrated in portable or fixed devices to detect and monitoring O3 concentration.

• Flexible pressure sensor 
• Long life span
• Low cost
