With the advances of ICT infrastructure and bio-sensing silicon solutions, in-hospital medical cares are moving toward home-care or even mobile health-care services. To meet this medical service trend, it is necessary to provide smart sensing devices which can sense vital signals and detect decease syndromes by taking user’s behavior into account. In addition to detection accuracy, low-power with unique features should be addressed when designing integrated circuits for this purpose.

In this talk, 2 chip solutions will be presented for prevention medicine (PM). One is a multi-channel cardiac signal processor (CSP) for ECG extraction and syndrome detection, the other is a field-programmable lab-on-a-chip (FPLOC) which is designed for bio signal detection with microfluidic operations. The multi-channel CSP, integrated with sensor interfaces, is designed for mobile healthcare applications. Applied with dedicated processing engines, the CSP extracts critical cardiac signal features based on compressed data with 90% storage reduction, while keeping the data and wireless link secure. Besides, the biopotential and capacitive sensor interfaces enhance the CSP functionality with least power overhead. Implemented in a 90nm CMOS technology, the CSP consumes 22.6-46.5μW at 0.5/1.0V in different monitoring configurations. The FPLOC integrates a set of basic operations on an array of 2-dimenional microelectrodes. Furthermore both control and detection functions are realized under each microelectrode, leading to a scalable design with limited I/O. Implemented in 0.35um CMOS 4-metal process, this FPLOC achieves 900 microelectrodes with a capacitance-to-digital measurement window in 3.2mm² and performs droplet moving at 1KHz and position detection at 1MHz.

Demonstration examples with these 2 chips will also be shown to highlight their potential applications in emerging PM devices and Big Data in Medicine.
