Market Drivers for Sensors

PAST FUTURE PRESENT

Automobiles Since 1980s Cars Are Now Full of Sensors

Smart Phones Last 10 Years Smart Phones Make Sensors Wearable

Wearable Devices IoT Home Health

< Slide 23 >

Common Sensors Now

•  Temperature •  Pressure •  Vision •  Microphones, Photodetectors •  Vibration / Acceleration •  Motion: Gyroscope, Accelerometer,

Magnetometer •  Heart rate / EKG •  Distance using RF signal strength •  Distance using ultrasound

< Slide 24 >

Future Of Sensors

•  Chemical Sensors •  Gene Detection Chips – Getting Better •  Lab on a Chip – for Fluids •  Paper Based - Disposable

•  Fiber Optic Sensors •  Pressure, Temperature, Strain, Force, Displacement

•  Non-contact Glucose Sensor? •  Big Data to Analyze Sensor Data

•  Make Sensors Smarter with Software

< Slide 25 >

Fiber Optic Sensors

•  Advantages •  Safe – No Wires to Sensor •  Small – 0.25 mm Diameter •  Operate in Harsh Environments, No EMI •  Multiplex Sensors on One Fiber

•  Disadvantages •  Support Electronics still Expensive •  Electronics Can Get Cheap in Volume

< Slide 26 >

Agenda

•  Trends •  Wearable Devices •  IoT •  Digital & Home Health

•  Sensor Innovation •  Current Challenges

< Slide 27 >

Current Challenges

•  Wearables – Batteries a Major Limitation •  Limitations in Sensors •  Islands of Data •  Are You Making a Medical Device?

< Slide 28 >

Battery Limitations in Wearables

•  Slow Pace of Improvement If Improved Like Semiconductors: Size of a Pin Head, Could Power Your Car, Cost 1 Cent

•  Must Always Work Around Limitations w  Short Time Between Charging vs Small Size w  Limited Wireless Transmission Range

§  ie Bluetooth instead of WiFi or Cellular w  Wireless Transmission in Short Bursts

§  Devices Slow When Listening for Transmission w  Use of Accelerometers Instead of GPS

< Slide 29 >

Limitations In Sensors

•  Low Cost Devices are Not as Accurate •  Non-linearity and Offset Errors •  Calibration or Auto-calibration

•  Challenging to Get Good Data •  Need Well Designed Data Acquisition Electronics •  Software Can Make Data Better

•  Cameras – Lighting Often a Problem

< Slide 30 >

Islands of Data •  Devices Collect Isolated Data •  How to get it to the Doctor? •  How to Collect from Many Devices? •  Will The Solution Create Electronic Health

Records (EHR)? •  Highly Regulated

•  Patient Confidentiality is a Problem •  Severe Penalties for Violations

< Slide 31 >

Are You Making a Medical Device?

•  Cell Phone App Can Be A Medical Device •  FDA Issued Guidelines for Mobile Apps in October 2013 •  FDA Can Force A Company Out of Business for

Violating Regulations •  Changing the “Instructions For Use” May Make It

Not a Medical Device •  Pulse Oximeter Example
