3D MEMS Technology: Small Size, High Quality and Low Power Sensors for Healthcare Devices



Healthcare applications account for approximately 15 % of the total value of the MEMS (Micro Electro Mechanical Systems) market, and it is expected that the figure will rise to 25 % by the year 2015. VTI Technologies, the global market leader of accelerometer sensors for pacemakers, is well positioned to satisfy this growing demand and to offer innovative MEMS sensor solutions to existing and emerging healthcare applications.


The growing demand in the healthcare sector is being driven by aging populations and continuously increasing healthcare costs. To minimize healthcare costs, more investments are being allocated to applications such as remote monitoring and treatments and diagnostics utilizing electronic devices.


Sensor technology in healthcare applications enables improved care and a better quality of life for patients. Sensors increase the intelligence of life supporting transplants, and they can be used in new types of patient monitoring applications that allow patients to lead more independent lives. Detecting signals triggered by symptoms helps optimize medication and prevent serious attacks of illness.


VTI Technologies’ solutions are based on the company’s proprietary 3D MEMS technology that enhances healthcare devices in many ways. For pacemakers, for example, accuracy, low power and reliability are the key parameters: more accurate activity monitoring means the patient’s heart rate can be adjusted to match precisely the needs of the patient. VTI’s unique MEMS design, which combines single crystal silicon and glass, ensures exceptional reliability, unprecedented accuracy and excellent stability over time. The power requirements of these sensors are extremely low, which gives them a significant advantage in small battery-operated devices. VTI’s 3D MEMS technology enables ever smaller sensors and batteries to be designed, thus meeting the miniaturization requirements of manufacturers of implantable devices.


Pacemakers are not the only healthcare application for VTI sensors. Based on the company’s long experience in pressure sensing technology, VTI is today well positioned to offer a wide range of pressure sensors for healthcare applications. Device developers and manufacturers of many existing and emerging healthcare applications have been able to reach their power and size requirements thanks to VTI pressure sensor dies.


For over 15 years VTI has designed and supplied customized products for medical device manufacturers with zero field returns. The entire supply chain, from design and manufacturing to testing and packaging, takes place at VTI’s own factory located in Finland. The factory boasts extremely strict quality systems as required by the automotive industry, another major customer segment of VTI for over 20 years.


VTI in brief VTI Technologies is a leading supplier of acceleration, inclination and angular motion sensor solutions for transportation, medical, instrument and consumer electronics applications. In their end-use applications, VTI’s products improve safety and quality of life. The silicon-based capacitive sensors are based on the company’s proprietary 3D MEMS (Micro Electro-Mechanical System) technology.
