Expandable 4-channel EMG Data Logger DelSys,
Boston, MA
Innovation - The DelSys MyoMonitor is a
4-channel portable data logger designed to
acquire and store surface
electromyographic (EMG) signals effortlessly and
reliably for up to 16 hours. The incentive for
this project was provided by NASA when a
need was expressed to monitor the muscular state
of Astronauts during missions. The
technology has direct applications in the
commercial sector for rehabilitation,
activity monitoring in home-care, performance
monitoring of athletes and research in
ergonomics. The device is being expanded
to accept 8 channels and can be easily modified
to store data from other physiological
monitoring sensors.
Accomplishments - The development of reliable
hassle-free EMG electrodes, requiring no training
or previous experience for use.This
electrode design has transformed the science of
Electromyography. - The ability to monitor EMG
signals in remote locations anywhere in the
world. All other EMG monitoring devices
are designed to work in laboratory settings,
limited by the need for bulky computers
and an AC power source. - The development of a
medical-grade double sided adhesive interface
system for securing the EMG electrodes to
the surface of the skin for long periods of time
and in adverse conditions without
compromising the physical condition of the skin
in any way. - The company has recently
established production and commercialization of
the EMG electrodes in quantities of up to
1000 per year. DelSys Inc. has grown 400 in the
past 3 years - The MyoMonitor compliments a
line of desktop EMG equipment and accessories,
including a two-channel, a 4-channel and an
8-channel system. All of these devices are
currently commercially available. - DelSys
Inc. has grown 400 in the past 3 years.

• Commercialization
• Trade-Mark applied for MyoMonitor within one
  year of product development.
• The MyoMonitor entered its commercialization
  phase prior to Phase II contract completion. Upon
  contract completion, sales on the device were
  already logged.
• Technology is covered by a patent which has been
  filed (Patent-pending.)
• Primary target markets include rehabilitation
  sciences, home-care monitoring, athletic
  performance monitoring, ergonomics. These market
  sectors provide a tremendous potential for a
  muscle performance monitoring system which is
  user friendly, can operate remotely and is
  completely portable. There are currently no
  other EMG systems available which can offer all
  of these advantages.
• The MyoMonitor-4 is currently available from
  DelSys Inc.
• The MyoMonitor-8 is expected to be available by
  November 2000. DelSys Inc. has successfully
  applied for and received 7 SBIR Phase I and Phase
  II Grants.
• Outside initial capital provided by CEO.
• DelSys Inc. is currently seeking corporate
  partners for entering the commercial market

• Government/Science Applications
• The MyoMonitor was designed specifically for
  NASAs needed to monitor muscle performance
• and fatigue in zero gravity environments. The
  device is unobtrusive and can easily be worn
  around
• the waist. An LCD screen allows the user to
  easily configure the device for a particular
  monitoring
• session, and offers a signal check to ensure
  the quality of the recorded signal. Batteries and
  
• memory cards can be easily swapped for
  continual operation. The data is reliably stored
  on a
• Flash media allowing analysis to be performed
  at other more convenient times and locations.
• Other USG interests include soldier fatigue
  monitoring while training and soldier
  physiological
• monitoring while in combat.
• We Estimate that NASA could achieve significant
  mission/project cost savings due applying the
• resulting technology from this SBIR
  innovation/product development.
